Who is this guy to tell me what kind of keyboard I need?

I have so many questions. I'm assuming you've just been using this layout for ages? I can't really think of a reason other wise. There aren't enough binds to make this functional for me in anything beyond a really basic shooter unless you got like some mmo mouse with 12 keys on it. Are you using arrows for movement? I originally thought maybe 1235 but you have those bound for other things on a second pass of reading it. This just seems horribly unergonomic to me.

Anything that requires more binds than the num pad has seems like an absolute nightmare because of the lack of modifiers.

Like as far as alternate keybinds, I'd say ESDF and get 12 keys in easy range (QAZXCVGTRW23 and maybe 1 and 4 if you have large hands) with 3 easily accessible modifiers. If you need to type, you also don't need to move both hands.
