Well, I know this is personal preference but I find it weird there are people they didn't like the class revamp at MoP. I mean... Warlock is so super nice now. Specs are so good. I know they did their best during the expansion to ruin their great work on the class, but -in my opinion- there is no other class so enjoyable to play. I know, there are people that disagree but I really like the expirience.
BUT they still try the best to ruin it
