currently got my main accounts. a couple lvl 80s and 70s etc,. and my other account that i got a little while ago has a 46 priest on it. no longer linked . what would be a fast way to lvl him using my main, quests, or dungeons. i got an 80 prot pally and 80 rogue, 70 lock, 70 hunter.. if either are better then another ..

ps. mainly looking at just getting to 55 for now so i can start dual boxing DKs.
