Running MT on my hunter, trying (for the 4th time) to do that escort quest (1st time I didnt know where it was, second time group broke up half-way through, third time group wiped too many times on boss, 4th time - this one - group broke up right after boss and didnt go back). Anyway, on to my story...
After the second circle room, the one where the escort starts, the tank says "ig2g l8r" and leaves the group. Yep, just before the boss room. So we're looking for a fifth (rather, I am) and one of the guys says "can the pet tank this?" I said "Idk, this boss is pretty hard." "Lets try it anyway!" So I pick up the lock in the LFG and say "I doubt this will work...lets go!"
We wiped on the first attempt, but our mage was a 70 in purples and blues so we figured he could just take any adds that spawn. Well, I ended up using res pet twice, I got combat rezed by the druid, and at the very end of the fight I'm the only one left and I kill the prince as the adds take me out. It was pretty sweet.
So I pretty much just wasted your 2 minutes with this post, but I hope it can be a good anecdote for the future.
