Power leveling is the term used to describe the process of leveling a character as rapidly as possible with the least amount of play time. It can be used from any level up to level cap. Contrary to what many believe, efficient power leveling does not require endless hours of grinding. The best methods of power leveling involve doing many quests in an orderly fashion.
As the first major content release of Battle for Azeroth, patch 8.1: Tides of Vengeance is adding a number of new ways to gear up, as well as increasing the item level of rewards from existing activities. Tides of Vengeance goes live on December 11th and will add most of the new content, but Mythic+ and PvP Season 2 will not start until the new raid, Battle of Dazar'alor, releases in January, at which time the item level thresholds will increase to the new Titanforge cap of 425.
Vol’Dun is the hardest and most tedious of the Horde Zones in Battle for Azeroth. It’s also probably the one that makes the most sense. Each sections of quests leads directly to the one you should do next. For all of these reasons it’s going to be best to get this one done early.

“Power leveling” is a term used to describe getting a character to max level in a short amount of time. Essentially, someone who is power leveling wants their character’s level maxed ASAP so that they can move on to “end game”—gameplay intended to challenge max level players. This is an appealing practice for seasoned World of Warcraft players due to the fact that characters are required to reach level 100 to participate in a number of the more intriguing game play options. In addition to helping a player achieve max level more quickly, power leveling differs from traditional leveling due to its focus on boosting experience points through the use of special items, promotions, and gear. Also, while traditional leveling tends to be quest-heavy, power leveling often relies on running instances rather than simply moving from quest hub to quest hub. There are several different ways to power level, and many of them can be used in combination with others for a truly speedy leveling experience.
