With my keypad’s 20 keys, I can bind 18 of them and set aside 2 for shift and control.
I have 54 keybinds with ease.

You could do close to that with a standard keyboard by moving keybinds around to comfortable things for your hands to hit.

I do think the modern action gaming sustems with 3-8 abilities and hitscan aim targeting is better... but I don’t see the lack of enough keys to bind as a problem with the style of game engine we have here.
