I think they went a little buff mad in ultra, should've just been minor tweaks as AE was pretty much fine.
I just downloaded ultra on PS recently as I've only been playing on live, and had a match against the no.1 ken on there. I was Hugo and for the first two games I owned him but fair play to him he fought back to win 3-2 but then the guy starts doing that annoying thing where they challenge you but when you select accept they boot you from the game
he did it a few times at which point I messaged him and politely asked if he was a retard.. never heard from him again
