Great ideas guys. Id only like to add one thing about targeting.
When I hit tab make it so I dont target the turrets/cover shield first. If they have 4+ turrets/shields down its a pain to have to scroll through all the targets to target players. I wouldnt mind if I could just click on the target, but most times trying to click on players when they are standing around a bunch or turrets/shields, just targets the turrets anyways so I end up having to tab cycle anyways.
