Has anyone here beaten the last mission on hard? I'm at a loss as to how to win the fight with the regenerating altar. The main problem is the bloodletters... they are extremely hard to kill because the moment they get low health, they teleport a huge distance away and start regenerating. It's hard to kill them even if you are using all three of your elites on one. And if you ignore them, the bloodletters melee you and slow you, and the final boss sends waves of fire that do about 1/6 of gabriel's health per hit. And not only all of that, but once the final boss starts sending the mentioned waves of fire, he teleports almost immediately when you get near him, even though most of your damage is melee. I'm at a loss as to how to beat this fight.
