Your consumables like ammo synth.
Well theres 1 unused button they could use for setting up hotkeys.
R3.
Clicking and holding a thumb stick for x amount of time allowing you to get heavy ammo without having to wait in ur character screen.
And if ur heavy isnt ready yet a prompt will show up with X:XX remaining.
And if there more weapon like murmur to change damage types set a stick click hotkey to right stick and swap damage types instantly.
Could be a usefull idea. Your thoughts??
