So I found the default controls to be a little clunky so I changed a few things. I was curious if you guys have as well.
My setup:
Circle: Melee (I'm used to this from always using Tactical in CoD)
D pad Up: Context action (hack, capture, etc)
R1: Crouch
D pad Right: Cycle powers
L1: Use selected power. I did this because some abilities (like Oberon's Smite) have to be aimed at an enemy before you can use them and I find it difficult to swipe the touchpad while aiming at someone. I use the touchpad for any powers that don't need to be aimed.
