I played the 4x DKs, Tokov, pally healer was healing. Pretty easy - 0 wipes.

1st boss one of my guys died because I wasn't ready for the WW.

2nd boss was easy as usual, got the achievement

3rd boss, two of the DKs died, but we still managed to down him, not too bad. He dots a player with a living bomb type deal that hurts party members near each other - this is a pain.

Loken was actually pretty easy. Even though I had a pally healing. I used magic shield on 1 out of 3 AOEs, and moved out of the rest with a side strafe. We got the timely death achievement too.
