No real problem to keep aggro with my pally, but we've got another problem since 3.3:
The jousting in HToC is next to impossible. We tried it 3 times and got wasted rather fast. Trash is as normal but the 3 nameds keep charging our toons left and right, we can't swap mounts as fast as they keep damaging us. Well, my main team doesn't need any more HToC drops, but a once fast and easy heroic is now a 15 dungeon deserter debuff cause it's just not worth the trouble...
