The First Boss: Having 5 x Tremor totems in the group made it easy - too easy. Unfortunately the only advise I can offer for this fight is DPS hard and fast and when feared try to pickup the group asap.

The Second Bos: Oh how I hate him! The higher your DPS the quicker you wipe when I attempt this guy I used to remove some +dmg gear so I wouldn't kill myself. If I survived the first MC I'd have him dead before the second one. The key was to dumb down your DPS because your are essentially fighting yourself.
