Why not just make burst fire a standard fire mode selectable beyond 'aimed' fire with the assault rifle? I find it gets annoying to toggle between the two modes of operation with the little click button (especially because it seems a bit bugged for me and sometimes doesn't click over). I don't see a good reason to separate out the fire modes, and unless someone has a good reason why the two modes should exist, I think I'd like to see the 'burst' fire mode incorporated into the standard right-click cycle options for shooting at a target (so when you right-click a target, it goes: snap, normal, aimed, burst, snap.)
