Disclaimer: I'm aware controller is the recommended way to play. However my disability makes thumb sticks functionally impossible to use so I play on KB+M
Now that I have the disclaimer up time to address my point. It would be nice, if I had the ability to rebind things like using the electrical pulse from implant to a dedicated button. Dual button presses are hard, especially when with my rebound controls the key combo is very un-intuitive. I'm sure this isn't a problem for people using a controller, I wouldn't be asking this, if I could use one myself.
