Professions: This may seem strange for a leveling guide, but the first opportunity you get, pick up both the Mining and Herbalism gathering professions. Not only will this allow you to track many various quest objectives on your map, but you also get a fair amount of experience whenever you gather. I'd put it at around 10% of a quest turn-in per gather. Since most of your wasted time in WoW is travel time, stopping to gather ore or herbs can keep your exp/h rolling as long as you don't go too far out of your way. You should only gather if it's convenient, and on the way to an actual quest objective. Don't make gathering your priority.
Changes were also made to levelling in earlier content with Legion's 7.3.5 patch. The level-scaling tech introduced in Legion not only be continued in the new continents of Kul Tiras and Zandalar, but was also be applied to content from prior expansions, allowing larger level brackets for lower level zones. Further, as previous expansions are now included in the base game, the level ranges for those expansions are now broadened, allowing players to spend more time leveling in preferred expansions and avoid others entirely. Some examples include a zone like Westfall having its level bracket (at 10–15 as of Legion) increased to 10–60, whilst continents such as Outland and Northrend sharing a 60–80 level bracket. The aim of this change is to encourage more player choice whilst levelling and to allow players to experience the full story of a particular zone without overlevelling the relevant quests.
I like to spend as little time as possible on transmog. 1-3 hours of farming a week is about all I can stomach, and I can stomach even less of it on the auction house. When you've got a thousand items listed, cancel scans get ridiculous. As transmog is best taken as a method of making passive gold over time, with little pockets of effort thrown in, do not waste your time undercutting constantly. Instead, adopt an approach that allows you to just post once or twice a day.

Unless low quality items have some known quest use or are coveted by other players, you should try to sell it as soon as possible to create bag space. Always (or almost always, see above exceptions) keep things like cloth, leather, herbs, or large stacks of white/gray items over other loot when you have to decide what to keep when your bags get full. It might be worth your while to invest in larger bags (10-20 slot), especially if you know a tailor.

As an example, I will take my server values to calculate how many procs you need to make up the price of one Magnetic Mining Pick (40 SS ore, 10 Platinum ore, 15 Expulsoms). Assuming 25g per SS ore, 20g Platinum Ore, and 55x the price of Tidespray linen to craft 1 expulsom in average (got the value from a previous post in this subreddit); 1 Pick is worth 5325g (not counting the elemental flux).

Was doing it at 52 on my lightforged paladin and it was easily the slowest zone out of the ones I'd done. Granted, I didn't have War Mode on so I didn't have any PVP talents, but it felt like about 40% of my time was spent waiting around for respawns or wandering around looking for mobs to kill to get a quest item that had like a 5% drop rate. Maybe I just got unlucky but I definitely won't be going to that zone again for future heritage armor runs.
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.
This new farm takes advantage of the level scaling changes implemented by blizzard.  Event NPC's like the NPC's found in the twilight outpost, scale up or down depending on your level. HOWEVER, your level also determines which loot tables each mob will have.  By using a level 58 character, you can successfully loot items in the 57 – 59 item range, a range which has some of the most expensive and well sought after transmog items in the game.  In less than 30 minutes farming this spot I was able to snatch up some glorious legplates[/URL] (on video) – worth a stunning 150,000g.  Watch the video for absolute details I suppose, but the gist of it is you need to create a level 58 DK, go to the twilight camps, and start the killin'.  Unlike before, an implementation of a daily event has changed the loot tables!   This spot is the new hot thing on the block.
4. Is there a guild waiting for you on the target server that you are satisfied with? Often times, I have transferred to a server, made a lot of gold and quit the game out of boredom because I was without a guild. Another aspect behind this question is that often times in guilds, you can get free flasks and materials to craft goods instead of spending your own gold. This will add up in the long run, whether it's free repairs or free abyss crystals. Remember, you can always send the crystals to another toon and sell them for gold as well.

When buying raw materials from the AH, keep an eye out for bargains. Choose only the cheapest items available to keep costs down. Try scanning the whole section of item listings in the AH to check prices; often the prices for stacks of items in the AH are much cheaper than individual pieces (for example, a single Thorium Bar may be priced at 3 , but a stack of 10 may actually be priced at only 2 per Thorium Bar) — you may spend more to acquire your materials, but you also save more and ensure larger profit in the long run. You can find a lot of terrific bargains this way.
This is by no means a complete strategy, just a bit of insight into how I believe many approach transmog incorrectly and burn themselves out on it before they can succeed. There are better ways to do this, and you're free to pump as much time as you'd like into it to try and improve the results. Whatever the case, just make sure you're enjoying yourself, because it is that much easier to stick to when it's fun.

“I think that there’s a lot of gray in the game and in our world, right,” asked Cobo. “And so I think that tapping into that and making things reflect the complexities of the relationships that we have between these key characters and then the player itself, and having the player be able to experience that from their perspective, is really what is one of the strong connecting hooks of World of Warcraft.”
Of course this is pure speculation, but who thought the token would be beneath 200.000 Gold again? But the only thing important for you is to calculate at what point you make profit by selling the tokens again. If you consider it, you should take the risk! Worst case scenario: You have a lot of balance to spend for Gametime, mounts, pets and boosts/services!
