They are tough. And that is good. They are fast and that makes it for a quite harder fight. They target from quite far away, dispel summoned rather easily and call up in their aid Rising Colossuses,Animated Weapons and even Revenants. All that makes it for a long and challenging fight and a whole lot of deaths. What I totally disagree, though, is allowing these already very tough targets to also be allowed to self heal themselves. This should be changed, IMHO. That they are tough to fight, it is ok. That their fighting might be full of deaths and trouble is fine. What I find intolerable is that after a very long fight one has to give it up because the damn thing has been able to heal back up, player run out of time to continue fighting and so all of the invested time ends up empty handed, with a lot of insurance gold lost and nothing to bring home. So, I would definately block the ability of these things to heal themselves up. They are already tough, they already call up their summons friends to help them, they are damn fast and shoot from well a distance. At the very least let us be able to do them damage little by little and that damage to stay, not go wasted because they can heal back up. By the way, Greater Dragons are useless against them and Rising Colossus, even casting Empowerment, get dispelled a go-go......... That's at least as I see it.
