I'm level 40, and I want to get to 55 pretty fast, so I have been doing dungeons since level 15, any advice on where to fight mobs at my level and get good xp? So that way I get xp while waiting in que for dungeon, also where should I be questing and how long will it take me from 40-55 if dungeons/bit of questing/slaying mobs. Please answer all questions thanks so much !
