Would a fighter pilot have to switch firegroups and potentially take his focus off dmg to ping a target? Please let us assign this to a separate hotkey.
It would still be nice to have a hot key option
I like the way the groups are arranged. The added complexity of having to select a firegroup that includes some of your weapons and kws or just weapons and just scanners makes for a more personal set up and leaves even the best with the chance of getting it wrong.
If it's really troubling you put weapons on trigger 1 and kws on trigger 2.
