I don't think I will bother with agility. I may get 30 or 40 quickly as it will take 30 minutes or so but other than that i'd say you are wasting your time. Stamina's will be the game soon.
Best thing I think is to just get tank gear and tank. All these people rushing ancients on the 7 day tourney are silly, they'll get rekt by 10 tanks in range/melee
