as a mage if you look on general there will you found the ability bloodthirst, you can't use it becuse it is for warriors and you need rage, the quest glitch is that
if i change faction to alliance and then back to horde i will be able to redo some quetses such as the vine and so you can get 500 honor and unlimited off Crusader's black horse, by redoing the quest to slain the alliance general at the pvp mall ( same with alliance only that you have to slain their boss)
