I hate to say this, but I believe I beat it 1 day before the patch. There were some big issues....sad to say After the pursuer and the vampiric attack guy....comes the death sands. I never got to see their skill as I killed them too fast. But I see some of them in heroic...on Justice helm #2 now.
Screen shots of 2 bosses when I fought them (graphics are badass) spoiler alert if you don't want to see them.

I just figured out how to use bloodstorm more effectively and have been running through things fast...cant remember much. by having him get hit a bunch...get his hp down to 10% then have him kill. helped me through a few tough guys recently. I've purposefully taken off def runes on him for that lol.
