Another way to handle the bleeds is for people to spread. It's small aoe targeted to player which can stack. It's not, if I recall right, targeted to same person twice. So if everyone take just one hit (the one targeted to themselves) they get one stack at most which goes away soon enough to not cause much problem. But since people like packs, they get hit by more of those than necessary. I understand that the melee need to stay close to ozzy, but on triangle phase there is no reason for people to stack apart from meteor avoidance.
