Well I guess the problem is my warlock (affliction) which is hard to box with a castsequence macro really effiiciently and then there is my priest healer with his 6500 health (or something) buffed - whirling around will take him to 60% - the ice block AE will take him to almost dead and then the whole thing starts again - I came once to the phase where she splits up. I'll try it again as soon as my gear is better.

Still thinking about swapping the roles, going from my elemental shaman to resto shaman and my holy priest to shadow priest ... maybe
