Most ridiculous thread ever, but on the other hand I cannot believe that 60 odd people have said yes, while 70 have said no, so perhaps not so stupid after all with such a split in opinion.
To take a 40 man raid design, morf it into 25 man, and then 10 man took some going so to jump down to 5 man is a step too far for me.
4 Horseman? What, shall Blizz re-design the encounter to be like 2 Horseman or something?
Not for me. Will never happen.
