We have a shaman that raids with us all of the time. He's rarely top damage, and recently, he hasn't even been top 3, not because his DPS is bad, just because we have well geared people in those top 3 slots. However, I don't care if he didn't have bloodlust at all, he's a great raider, knows what he's doing, listens well, and he's got an offspec of resto if we need it (but that's rare). He would be in my raid regardless because of those factors, not because of bloodlust.
Now with prehensile ears!!
