You should change the controls, specifically the weapons, to be individually mapped along side of infantry movement, helo, planes, etc. What I mean is, let me map a different control to fire my weapon when I am an infantry, like the right trigger on my xbox controller. However then when I go to my aircraft, I would like my right trigger to run my right pedal. When weapons have their own category it can really screw up bindings like that and almost makes playing with a controller useless, since you can't transition roles without remapping the whole controller. Another fix could be saving keymap profiles, then at least when i use different control schemes I could just go into the controls, load up the profile for infantry/piloting/ etc and that would be much quicker then having to remap the entire control scheme.
