Waypoint System with Taxi Feature - Works similar to TomTom, clicking the Quest POI in your Objective Tracker will automatically place a waypoint for the quest. The waypoint arrow will turn green if you enter the selected quest area. You can also create your waypoint by CTRL + Right Click on your map and you can also link them together by holding SHIFT + Right Click on your map.
Power leveling is the process of handing over your character to another player (usually it's a seasoned WoW player), who then gets your character to the highest level possible in the shortest amount of time. In essence, someone else does all the hard work for you so that you don't have to waste your time by leveling the character/s yourself. And as with most other MMORPGs, there are a lot of players who offer such power leveling services for World of Warcraft.
We have no idea what implications this might have and whether or not it even indicates anything, since Patch 8.2 is still in testing and a Tuesday launch is more than unlikely due to Essence tuning and Azshara's Eternal Palace, which is supposedly coming shortly after launch. Blizzard said they wouldn't be delaying the new raid like they did with Battle of Dazar'alor.
