I just got the game today for my ps4 and found the controls to be a bit stiff (ADS is the worst), especially in the pre sequel (which of the 3 games I have yet to play) which I hope will be addressed in a future update.
So anyway. I started playing borderlands 2, which I haven’t played any of the addons for and had to use the restroom. so i grabbed my faithful vita started up cross play and found that though cross play is supported the vita control scheme is way off. I dont usually use my vita except when I’m away from my Tv so I dont want to keep changing control schemes after every switch. so hopefully you can work on a control scheme. =]
