Okay, my guild have progressed through ICC theese days, downed it all on 10man and have the proffesor and Rotface left in 25.
The problem we're facing is on Rotface. Everything goes smooth to about 30% where he starts to put up mutated infection on a greater speed than usual. On 10 we just poped BL at this point and nuked him down, leaving healers to heal the infected people. But I'm not sure it's going to work on the 25 man version.
So, my question is, what does your guild do to tackle this problem, or is it just our guild that lack those extra braincells to do the job?
