MoP was the final nail in the coffin of WoW for me honestly. The game is nothing like it used to be. They've added things to the point it no longer feels like WoW to me, and that makes me sad. There's no challenge left to be had, no skill required, and the gear and spell inflation is just way too out of hand. Add in the extreme level of homogenization and this game might as well have four classes.
The game feels too fake at this point. Take me back to TBC, heck maybe even WotLK days and I'd be happy.
