... I'm curious why you would even want to discourage peeps from using the quick switch? Why wouldn't quick switch always be the preferred method? Is there some technical limitation being addressed by this? Potential crashes or frame rate hitches if the player spams it?
I'm probably missing something because quick switch sounds super useful and purposely nerfing it just seems like it could feel frustrating and clunky to control. (plus, I can immediately think of gameplay/boss AI that could focus around the idea of having to switch beam types quickly)
I say embrace the quick switch. IMHO. ;)
