I use an Azeron Cyborg controller because I have found that it helps me with some ergonomics issues in my hands. I’d love to be able to use the analog stick on the controller to move my character while keeping the rest of the game (aiming skills, buttons, etc) using mouse and keyboard.
I’m sure there are other accessibility solutions that rely on being able to use hybrid controller/keyboard controls too, so I don’t think this is just a me thing!
