Nothing is really changing in Mists. Blizzard is simply putting a new coat of paint on and hoping you don't realize it. Rotations for all classes are almost exactly the same, almost all abilities are exactly the same, and raiding is the exact same idea with new npc's.
You expect us to play the nearly the same classes we have been playing for 7 plus years and not be bored? Doing the same thing over and over again and expecting different results in the definition of insanity. No wonder why people are leaving your game in droves because you refuse to change blizzard. You would rather lay in the pool of stagnation and watch your game slowly die instead of boldly taking risks and changing things. Jesus would a few radical ideas really hurt that much?
You are not even the same company you were before blizzard. You accumulated so much by having the heart and guts to take risks. It is as if you have been blinded by fame and fortune and have forgotten where you came from. Another problem is you refuse to higher anyone with new ideas. You say it may corrupt your talent pool, but is this really true or just another cover up because you are afraid of change?
