I read this on another forum. People are saying they can do 1-80 by having an 80 boost RAF toons to 60 in dungeons then going to outland and northrend and doing dungeon tagging. They claim that the booster can be the party leader and once a group of mobs is tagged everyone drops party AOEs the Mobs down then gets back into party and the Party leader gets all the xp like they soloed the mobs.

I thought tagging was nerfed but these are recent posts. Anyone confirm or deny this?
