Im in a similar boat myself, I just don't feel like playing any more. It's such a hassle and headache between the connection issues (I will.give them credit mine has been a lot better since a patch or two back, but still not solid by any means) frame stuttering I'm getting now (in a game where one frame matters, stuttering is a huge deal), lack of and massive delay of, important balance and bug fix patchs..
It's just sapped my motivation to give a damn. I spend more time worrying about whats going to go wrong. Or how my version stacks up vs the console (balance wise) etc than I do enjoying the game. Not to mention when I finally am able to lose myself in mkx, frame stuttering starts and gets worse over a match or two until.its unplayable and i have to restart.
Shrug. I still have some hope for mkx, but they aren't high. Until.they get shit together though, I'll be learning SFiv and looking very forward to 5.
