I think the Golgoroth and Warpriest sections of the raid were well done. They struck a good balance between mechanics and shooter. They kept moving and there was a slight degree of chance as to who would get the green glow for Golgoroth or who would take over the aura if someone died at warpriest. The sisters portion was fine albeit a bit frustrating trying to get the whole team to damage them while you're practically blind and they're dancing around like an epileptic fish out of water. Oryx on the other hand was too long, overly technical, not terribly action packed and very unforgiving if you made a mistake. Add the requirement for a long quest item gun that was useless everywhere else in the game (touch of malice) and it was too much.
