A guy leveled 1-90 as a pacifist, the first ever to do it. It took him 9 days to hit 85 and another 12 to get to 90. He did no quests, pvp, dungeons, raids, no combat of any kind. Only exploration and professions. Pretty impressive.
Shit! I don't know if I would have the willpower to level to 90 in 21 days the easy way. I have toons 9 years old that are still in their 40s. LOL
