For Heroics- My pull key has swipe on it also. When they get to me I get in 2 swipes, make sure they land, then go to the tanking sequence. If I do this the aoe won't pull them off.

My sequence is a mangle, lacerate, swipe, lacerate rotation. I want to keep ahead on the threat and lacerate/swipe have a high threat modifier.

I don't raid with my bear. I only do 5 mans. If I attend a raid it is always on a shaman lol.
