As I guess you all know, Amphitheater of Anguish are the wotlk version of Ring of Blood. What I am going to explain is how to abuse this questline to gather XP rather quick. I am also going to tell you how to wtf annoy ppl in this new ring of blood.
What to do: Either you, or someone else pick up the quest with the mammoth. Keep killing the guy until the mammoth spawns. Jump on the mammoth and run out of the ring and start kill mobs for quests. He does quite nice dmg + you get to ride him for 5minWhen the 5 mins r done you can do it over again!
How to annoy people? If you want to annoy people, you can taunt the quest-mobs and drag them away from the ring, then they reset. And you can then pick the quest up yourself if u wish =)
