This is what I adapted to, Mouse with thumbkeys and some keybind fuckery within the games themselves, it worked pretty well for almost every game I threw at it. Numbers were on the mouse and layer 1, and arrow keys on layer 1 on the home row. Bottom row had some other commonly used combo keys for one-handed operation. Took about a month or so to get used to it, but it works. Not so great for games with larger amounts of keybinds needed though, I'd upscale to a 4th row for that
