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.
Dugi’s leveling guides cover everything from level 1 to 120, for both Horde and Alliance, and any race and class you can think of. You get an addon that you load inside the game which shows you step-by-step how to get to the maximum level in a streamlined fashion. There’s even a waypoint arrow that shows you the direction you need to go, so you’re always on the right track. The addon instructs you which quests to pick up, where and how to do them, when to turn them in, and even other features as well. Dugi guides have been around since 2005, so they’re probably going to be around in the future as well, keeping everything up to date and current.
Prior to update 7.3.5 it was far too easy to level up a new character. The experience needed to advance from one level to the next was too low, resulting in players out-leveling the story quests in each zone, moving on before getting the full experience. With low monster health and high player power (especially when players were outfitted in ridiculously powerful heirloom gear), creatures dropped like flies. Combined with easy experience gained by joining parties in the dungeon finder, the first 60 levels in the game flew by.
Allowing WoW Tokens to be used for Battle.net balance creates new demand for tokens. There are some players in WoW with lots of gold who have considerable excess even after paying for their subscriptions with tokens. There is a limit on the amount of subscription any player can use, and that amount of tokens doesn’t make a dent in the gold hoards held by some players. Now, assuming those players want to buy stuff in other Blizzard games, they have incentive to buy a lot more tokens.
The older brother of this potion originally came about in Cataclysm as the Potion of Treasure Finding, and is actually one of the best ways to make money. Since most Pandaria mats are constantly farmed, they usually sell for less than the Cataclysm mats. This makes using this form of the potion more effective for making gold. Not to mention that creatures die faster to level 90s since they were made for the previous expansion, making farming the treasure chests that drop rather easy.
The zones in Battle for Azeroth are littered with treasures and rare spawns that give the same amount of XP as quests. With Zygor's Leveling guide these points of interest are displayed directly on your map and can be clicked at anytime to add them underneath your current guide step. The guide will then switch focus to the POI, direct you to its completion, and tell you how to complete it.
Something to keep in mind as well is that this will make enchanting materials more valuable, since it is likely most players will now simply scrap their boe greens instead of getting them disenchanted. Also redundant dungeon/raid gear can be scrapped rather than traded to the (guild) enchanter in the run. Less stuff gets disenchanted, meaning there will be less ecnhanting materials, meaning their value will rise. All the more reason to DE rather than scrap as an ecnhanter.
