so with the changes to quests dungeons etc.
how long does it take now to level from 1-100?
im pretty sure that blizzard will nerfed dungeon XP in order to "encourage" leveling while questing.. so that the world seems "more populated now".. and since everyone is happy to buy some characterboosts im pretty sure that they drag out the levelingprocess just enough to convince people to "just buy a boost already!".
and every whiteknight will agree.. because you can buy a boost there is no problem with outdated 100times played content to take weeks to complete all of a sudden because they want to give you "a better experience while leveling"... (sorry blizzard but your game is not skyrim where questing and exploring the world is actually fun.)

(i hope im not right)
edit: the first XP nerfs are documented on the frontpage.
