Too many times I've used F to switch back to semi-auto mode only to find that I was using the grenade launcher, sometimes with fatal results to either me or my innocent teammates. I have three suggestions I think would solve this issue:
- Assigning a different key for switching to the grenade launcher.
- Changing the grenade launcher representation on the upper-right corner to something different to the semi-auto's.
- Having a different button entirely dedicated to firing the grenade launcher. This might not be the best idea since not everyone has extra buttons on their mouse.
