You do know the pad as been through fairly big changes on the PS4? The triggers are now triggers instead of being bent the wrong way so your fingers drop off.
Will the old Button 1 now be the trigger thought ?
on the PS3 button 1 was always ADS and fire which annoyed the hell out of me and on BF3 couldn't be changed round !
It was the same on COD too, but at least COD let you switch them round.
