Quality gear. These can be greens, rares, whatever. However, always think, "Who needs this?" Items that have stats like Stamina are typically useful to all players. Items with stats like Spirit are only useful to a subset. Items that combine two highly sought-after stats, like Stamina and Intelligence (which all casters need) will sell for more than items that combine two stats like Agility and Spirit (which practically no class needs).
Many players who already have higher level characters create alts that they level to a certain point and then stop. Often, these twinks are level 18-19, 28-29, 38-39, etc. for the purpose of going to battlegrounds at the top of their tiers and kicking butt. Since these twinked characters are owned by higher level players with lots of cash, they usually outfit them with the best gear available at their level. Thus, items that require level 17-19, level 27-29, or any other items around this level, with good stats or dps, often sell for much higher prices than they normally would. This is especially true on an older server, and also especially true of blue (rare) items. In general, "good stats" include Cloth "of the Eagle" (for mages, warlocks), Leather "of the Monkey" (for hunters and rogues), and Mail "of the Bear" (for warriors/paladins)as well as weapons with these suffixes that can be used by the right class.
While it’s clear that Blizzard is eager not to spoil the future of Battle for Azeroth, it seems pretty unlikely that players who want to be pure evil will ever get their day to shine in World of Warcraft. Despite the decision being added into the game, the good guys will likely win and the threats to Azeroth will continue to roll on by, getting knocked out by players one at a time.
An alt (low level or no) in a capital city is an effective way to not only cheaply increase your available bank space, but to be a simple savings and auctioneer account. This character can serve as your bank, an auctioneer, bag-space creator and a time saver. Get one. (There may or may not be Item Recovery issues with characters below level 10, in cases where one's account is hacked.)

Anyway both got to 110 at around 50h played. I messed up with my Pal by going to Legion once I hit 100 instead of finishing treasures and bonuses in WoD. All in all, if I picked the best zones and was only trying to level as fast as I could, I would probably could have done it in roughly 40h. Note that it would have a been A LOT faster with a Monk as both Ret and Rogues don't really have a decent AoE until 40+ (45 for Ret and 63 for Rogue I believe). The daily also helps a lot. I know that leveling my Monk before the pre-patch was insanely fast. Might be slower with the changes to FoF, however.
Once you are level 21 or 22, you can head over to Kalimdor and the Stonetalon Mountains. The entry level quests towards the south entrance (concerning the Tauren) may be to low to be worth it, so head north to Sunrock Retreat and grab every quest that you can. Once you've completed all of them make sure you are at least level 26 before we head to the next zone. Grind it out to level 26 if you need to.
Engineering is a crafting profession that primarily revolves around fun recipes. The gold-making potential from engineering is limited in terms of Legion recipes. The Skullblasters can be obliterated for profit. Engineering has a lot of profitable old world recipes, primarily mounts and various unique effect items and toys. This profession is best relegated to an alt unless you love the lore-aspect or have other sentimental reasons to keep it on your main.
This level range opens a variety of zones from the Cataclysm expansion, which are spread across the game’s original continents, but it’s more efficient to head to the continent of Pandaria. You can spend the entirety of this level range exploring its uniquely themed zones and quests. The Jade Forest, Valley of the Four Winds, and Kun-Lai Summit are our picks, but all the zones are worth checking out.

Vigilance Perch is essentially an automatic mount when out of combat. Despite its tooltip, it only allows you to fly in flying zones, so you will not be able to fly in Battle for Azeroth zones. This is a great Legendary to pair up with Sephuz's Secret. Choosing between this and Apex will come down to personal preference and how you prefer to level. When speed-leveling with consumables, you will not get full value out of the mount ability of this Legendary. If you are just leveling normally, try them both out and see what works best for you.
Jewelcrafting also offers players the Prospecting ability; players can break down most Mining ores to find gems used in Jewelcrafting. The Enchantrix addon can calculate the prospecting value of an ore, and when combined with the Auctioneer addon, you can compare the prospect value to the ore's value and determine whether it has a fair chance of producing a profit. For example, on most servers Tin Ore has a significantly higher prospect value than the ore itself, and players can make a tidy profit by prospecting tin from the AH. The low skill needed to prospect tin ore makes this a great profession choice for bank alts!
The entire Jade Forst is our farming spot for this one.  Literally, the entire Jade Forest.  The Jade Forest is crawling with porqupines and if you have a mage character, each one of them has chance to drop the polymorph porqupine tome.  Which is excellent, because these tomes have a selling point of 13,000g across the board. They are really easy to get, and noone really pays attention to these spots.  Try it if you like, I was able to get 2 on video, and have already sold one of them.  
Sep 1 Blindsight's How to Choose a Server Guide [Originally posted by Blindsight-Spirestone on the old Warcraft forums--it's my understanding he no longer posts, but this is a valuable and informative guide] Since it's a frequently asked question on these boards, I've thrown together a quick guide for how to pick a server. Server Datacentre Location - New York, Chicago, Phoenix, Los Angeles First and foremost: Limit your search to servers that are as close to you (physically) as possible. Closer servers will have better latency, and thus deliver a better play experience. WoWWiki has a great list by datacentre: http://www.wowwiki.com/US_realm_list_by_datacenter Realm Type - PvP, PvE, RP, RP-PvP Now that you know which servers to look at, the next most important question is if you want to play on a PvE, PvP, RP, or RP-PvP server. RP vs. non-RP servers should be a simple choice: when interacting with other players, do you want to act "in character" replying to other players like they're living inside the world of Azeroth, or would you rather just play WoW like any other video game treating everyone else like a player at a keyboard? If you want to play on an RP server with active RPers: "Wyrmrest Accord and Moon Guard are very popular, but Moon Guard is very over populated." -Nok PvE vs. PvP is a bit of a tougher decision. On a PvP server, once you get to about lvl 20, in just about every questing zone you go to you can be attacked at any time by any player of the opposite faction (Horde vs. Alliance). If you like the idea of jumping other players while they're running around killing mobs/questing, this may be for you. If you don't like the idea of a max lvl player killing you in 1 shot when they ride by, then you may want to stick to PvE servers. Some people feel that PvP servers have a slightly more mature community since most children and/or immature players can't stand being killed randomly. Other people feel that PvP servers have a less mature community since it's full of teenagers who like to grief other players while they're just trying to quest. YMMV. Realm population - New, Low, Medium, High, Full The next major consideration for choosing a realm is the realms' population, both the total number of players and the Alliance / Horde ratio. This is a bit more complicated, and there are different ways of looking at the data. First, WarcraftRealms.com has a tool for taking a "census" of various realms, but it relies on data uploads from players on the server. Its data is only as accurate as the data it receives from player uploads, but it gives a pretty good baseline idea: http://www.warcraftrealms.com/realmstats.php?sort=Total Another useful way to look at population data is in terms of server age. Older servers tend to have higher populations. WoWWiki has a list of all US realms' creation dates: http://www.wowwiki.com/Timeline_of_the_creation_of_US_realms So that's great, but what does it mean? How does population affect the game? Here are a few points to consider: Empty servers: By far the easiest way of ruining the MMO experience is to have nobody to play with. Avoid servers with very low population. Queues: Very high population realms often have queue times. This could mean waiting for half an hour every time you want to play during prime time. During prime time (weekday evenings and weekends), check the realm status page to see if the server is listed as full: http://www.worldofwarcraft.com/realmstatus/ Economy: Higher population realms have more robust economies. This means the auction house will have many more items listed and will be much more competitive. 10/25 Man Raid PuGs: Higher population => more things happening => more groups going all the time. Pick up Groups will form more frequently and will fill faster, meaning you can play more and sit in town waiting for groups less. This also, however, means (on some servers) that PuGs can be more picky in who they take along since anyone can be replaced quickly. A/H ratio: Depending on how you like to play, you may want an even ratio so that everything that involves opposite faction interaction (like world PvP) are more fair, or you may want to be on the advantage side of an imbalanced ratio so that your side is usually winning. The only disadvantage with being on the plus side of a wildly imbalanced population is that soon, world PvP zones (i.e. Wintergrasp) will only allow the same number of players (beyond a minimum level of 20 players) from each faction in at the same time, so if nobody from the other side shows up, only 20 from your side can get in.Frejya117 Sep 1
The recruit also grants the recruiter levels, with the latter gaining one level for every two levels the recruit gains. There are a lot of rules and restrictions to that, however. It all basically boils down to leveling alternate characters together. The recruiter can even earn epic mounts and battle pets if you stick with the game for a couple months.
