I am sick of silent battles.
My suggestion:
You get 5/10 slots where you can write floats for your character to say in battle.
Various preconditions - Just been shot, just been critically hit, just shot someone, just scored a critical hit, on severely wounded, on almost dead. That kind of thing.
When these conditions are met, your character will say this PRESUMABLY HILARIOUS line mid fight without you having to do anything.
Just an attempt to add some expression in a time where you're normally frantically clicking and too busy to type witty asides.
