I saw a post a couple days ago about someone telling PS4 players to change the default L2/R2 back to the old L1/R1 on PS3. Obviously on PS3 I kept the default L1/R1 but ever since playing on PS4 I can't go back and the shape of the controller is part of that reason also. I forgot that the default setting on FPS for PlayStation was L1/R1 the only FPS I have for PS4 are BF4 and BF1 so when I played remastered (which have the default PS3 settings) I was shocked like whoa prior to battlefield on PS4 I would never play with the triggers but its so much more efficient for me to play with the L2/R2 triggers now as opposed to the bumpers
