Sniper:
It’s a bit slow to switch from scoped to unscoped (after firing a shot). I like to scope, aim, fire, and then (just after having pressed mouse1) unscope really fast. But atm, all that feels kind of sluggish/slow. Maybe it is a pre-alpha thing, and it will be fine tuned soon.
Switching from sniper (scoped or unscoped) to pistol, and back, feels nice.
