When did Wow start losing its appeal to you?

The later part of Cata had me wondering what direction the game was taking. I gave blizzard the benefit of the doubt and bought Mists hoping they would find their stride again and deliver the great content they usually do. I enjoyed some parts of MOP (some of the raiding encounters are great and the music is fantastic) but the expansion has had more cons then pros for me. I've had to accept that blizzard is developing the game for a different breed of player at this point and that its probably best that move on. I'm curious to know what your thoughts on this matter are.
