Currently, it is believed that the War Mode rewards will change depending on which faction is more heavily prevalent with War Mode activated. The Horde have typically had more participating in War Mode, so the reward has been increased for the Alliance to incentivize more participation in War Mode. These rewards could potentially be increased to both the Horde and Alliance to incentivize both factions to higher amounts of War Mode participation.
8.1 unlocked a new level up state for epic champions that gives them 2 equipment slots, so I thought to reconsider which equipment should my BFA champions have in order to maximize gains. I saw a lot of negativity in other post about champion equipment (https://old.reddit.com/r/woweconomy/comments/ad6uzb/is_champion_equipment_worth_it/). IMO, the mission table has the best effort/reward ratio in the game, as in you just click things and some time later you get results.
Level 65 unlocks Greater Invisibility. This can be used to instantly escape combat with any enemy, or reduce the damage of big hits by 90%. Keep in mind, when using Greater Invisibility, you will drop combat, and lots of enemies will start evading and healing back to full Health, so do not use this on low Health enemies if you would survive the hit.
The tail end of Legion saw the introduction of Allied Races, which introduced two new races for each side to play as. Battle for Azeroth introduces more, with Dark Iron Dwarves and brown-skinned Orcs included in the upcoming choices. Blizzard hasn't confirmed much about what other kinds of races might show up, but there's plenty of datamined info out there for those who want to take a look. Allied Races start at level 20 after a short scenario and players can earn a special set of cosmetic armor if they level the character all the way to 1110 without buying a level boost.
Herbalism is also a good source of money. Herbs are required by alchemists and scribes. Unlike ore which is found only in rocky areas, herbs can be found in many places. Be sure to check on the auction house for what herbs are in demand for a high value; often a lower level one is very valuable, so you can farm an area you already know for quick money.
EDIT: Apparently this transmute *does* share a cooldown with other transmutes outside of the TBC transmutes. So again I would check prices on your server and make sure it's worthwhile to have and use this transmute instead of certain other ones. I believe it shares a cooldown with all other daily transmutes, even those that aren't listed in the profession text as a daily cooldown in game. Kinda unfortunate, but again I'd say compare prices and check the stock of Primal Air on your server because it could still be a great transmute to have if the stock is low on your server.
Most classes in World of Warcraft start at first level, but Death Knights and Demon Hunters are exceptions. They start at level 55 and 98, respectively. This alone can shave a huge chunk of time from your leveling experience. Of course, it only works if you want to play a Death Knight or Demon Hunter, but they’re both solid classics that can dish out damage or tank in a group.
If i start on a new realms, I am farming a lot of transmog from classic and Burning Crusade Dungeons and Raids. In the beginning, i start to post them if they have at least a DBRegionMarketAvg (Average value of an item on all EU realms of the last 14 days) of 500 Gold. All the other items get vendored. The time you hit a stock of 1000 Items, my value treshold raises to around 2.500 Gold. All the items below that value get vendored aswell. Newly farmed items that are above these treshold will be listed. Why? If I start over somewhere, I want to get a certain amount of gold quickly. Cheap items are great for that. Later on, to save time, Quality is better than quantity. As mentioned above, re-posting the items on the auction house takes quite a bit of time. At this point, I can recommend you the TradeSkillMaster AddOn, it makes your auction house work really a hell of a lot easier.
