Try monkey runs*, with a dedicated team you can actually hit up some nice millions xp/h. I find it more entertaining than questing


*Monkey runs = You group up with 5 ppl and use the LFD-tool for stormbrew dungeon and kill all the monkeys in the party room. They give around 8k xp/monkey (I think?) so with a good team, you should be able to get around 400-500k/round and every round takes 2-3 minutes maybe? So..Try that out
