Be cold-blooded about admitting that you've taken a bath on an item. If you bought that sword for 5g, listed it for 10g, and the listing cost is 2g50s each time, after two times it had better sell just to break even. Once you hit that point, don't keep listing it over and over in desperation trying to make something off the AH. D/E it, or vendor it, and move on. Lesson learned. Don't get trapped in the fallacy of sunk costs.
Take breaks. Unless you're straight up no-lifing it over a weekend or something, this leveling process is going to take ~40 hours. But any time you do need to step away, log out. That tiny little bit of rested exp is insignificant...but you never know when something might come up and you'll have to leave for a longer period of time than you expected. Better to be logged out and safe(especially with War Mode on) than AFK waiting for a d/c. Plus, you'll need to stretch, eat, shower, and maybe sleep. XD
Azeroth paid a terrible price to end the apocalyptic march of the Legion's crusade—but even as the world's wounds are tended, it is the shattered trust between the Alliance and Horde that may prove the hardest to mend. In Battle for Azeroth, the fall of the Burning Legion sets off a series of disastrous incidents that reignites the conflict at the heart of the Warcraft saga. As a new age of warfare begins, Azeroth's heroes must set out on a journey to recruit new allies, race to claim the world's mightiest resources, and fight on several fronts to determine whether the Horde or Alliance will lead Azeroth into its uncertain future.
You should try and quest efficiently - pulling several mobs if you can handle it, using your burst cooldowns while questing to kill everything faster. Many people would think that a 10-minute cooldown like Bloodlust is useless in open world, but you can do a "kill-15-mobs" quest in like 30 seconds if you pull a lot and use it. A free quest every 10 minutes is not that bad.
This kind of storytelling comes with problems, ones that players have been facing since the early days of the silent video game protagonist. Players in World of Warcraft have so much agency and choice when it comes to their own characters and how they build them. But despite their importance to the world itself, they can do nothing to change its story.
Drustvar is far and away the hardest Alliance zone, which is exactly why you want to do it first. If you have legendary items, they’ll still be usable, and if you don’t, this zone will still be easier early on than it will be later. Drustvar is also extremely fast and will let you jump out ahead of your competition in other zones, which means fewer players around to take your quest objectives.
Lightforged draenei - "For untold millennia, the Army of the Light waged war against the Burning Legion throughout the Twisting Nether. The draenei most committed to their long crusade would undergo a ritual to become Lightforged, infusing their bodies with the very essence of the Holy Light. After finally achieving victory on Argus, the Lightforged Draenei have undertaken a new mission: protecting Azeroth from rising threats and helping the Alliance push back against Horde aggression."
A little bit about myself for credibility: I am a 21 year old college student and have been playing WoW since it was first released. I have three characters at the gold cap and want to share my methods with you in a way that I hope has been more clear and concise than the other guides out there. Thanks again and check back soon for my role-playing guide for WoW as well as other guides for MMOs and RPGs in general.
Azeroth paid a terrible price to end the apocalyptic march of the Legion’s crusade—but even as the world’s wounds are tended, it is the shattered trust between the Alliance and Horde that may prove hardest to mend. As the fires of war continue to roar, take the battle to both new and familiar lands with the Tides of Vengeance update, and join your allies to champion your faction’s cause.
Elemental items (Primals, Eternals, etc.) can be a good source of money, because they are always in demand on the AH. See which mobs you will most benefit from farming, then set out for a few hours. In the process you will also most likely collect significant vendor trash, and may get other profitable item drops as well. Note, however, that older elemental drops usually lose profitability compared to newer ones, i.e. Primal Water sold well to level 70 players in BC, but sells far less well to level 80 players in WotLK, because level 80 gear requires Eternal this'n'that.
I recommend not counting on transmog sells for your monthly gametime. Its a great market, but also pretty random. You have to have the right items posted at the right moment if a player needs a certain item. If this is not the case, of course you will not sell anything to him. There are people making millions of golds a month with transmog. But they are very professional at it and it really takes a lot of time.
