Well, i found a place in Nagrand, on map you can see "Laughing skull ruins" There is a couple of ogres and at the left of the place, you can talk to a little guy called Gurgthock, he gives you a quest, that you can repeat 6 times, its bugged so you complete it immediately, that means, free exp and gold, because, each time you click complete, it gives you 11 gold and 60k+ exp, so that means free 360k+ exp and 66 gold ^^, try it, you need lvl 65 for the quest
