It happens to me a lot. Where when i try to use sprint it will just be a laggy sprint (the game is not laggy). And i have to click sprint again to get to the normal sprint. And then sometimes there will be some matches where i cant sprint at all because throughout the entire match it will just be a laggy sprint (same speed as just walking). And all these games generally are not laggy at all.
I've had the second one happen to me, where you hit x and you can't dash. For some reason in my instance it mapped my x ability to left or right bumper, I forget which. But my Y and B buttons were normal. It works itself out around halfway through the matches, for me at least.
Lol I figured out how to **** with that laggy **** and go endlessly faster. It doesn't actually help but it's funny. i see people abusing it all the time. they'll fix it soon i'm sure.
Yeah, i've had the happen to me a lot lately. It's quite annoying when trying to get back to cover only for my assassin look down and make sure she isn't stepping on any cracks in fear of breaking her mothers back...
