I have a three crew warlock team that just reached 80.

Demonology through the whole grind. @ 80 respec to Destruction.

Have thrown one lock in with my Shaman crew and straight off the bat, in full crafted gear but NO badge gear, it is equalling and often BEATING the badge geared shaman.

My main problem is that the lock is a freakin agro whore. It is pushing my tanking well out of the comfort zone.
