SV hard has shown some strange hate issues for myself and my healer. I have to fight him for aggro constantly (something that is not an issue in any other dungeon) and if a mob does get on him, almost no amount of moves on my part will pull it back off before it kills him flat out. I've noticed some difficulties in other parties as well, though its most noticeable there. We've been watching it after a few runs and its most certainly not an issue of player performance or item level. I'd be curious to see if this is some sort of bug or...I don't even know. But it does seem to happen ever since 2.3
