So I noticed that I was getting hand cramps and lasting pain after playing on my PC which I rarely get. Then I started to notice that it came from playing Overwatch. Because of the constant movement and the quick fast switching, my left hand was cramping up fast.

After looking up some solutions, I first tried connecting my PS3 move controller to my pc which did work but has my on-screen prompts constantly switching between ps3 controller buttons and keyboard prompts. That was a bit much.

I had to do a bit of digging to find a company called Splitfish. Although they seem to focus on the niche market of providing mouse-controls to the console market, they do have a controller called a fragchuck. Basically a move/wii controller for your pc for your left hand with enough buttons for all your regular controls.

I've had it for two days now and it performs exactly as expected. Together with my Steelseries Rival 500 mouse I have all the control I need to play Overwatch without the hand-cramps. It does need some getting used to since you need to create all new muscle memory because you're basically playing with half a controller and a mouse. But it works!

So if anybody is also looking for this solution, I hope this helps!

I've always wondered how it'd feel having both analogue movement and mouse aiming (basically the best of both worlds with console and PC FPS controls). Would you recommend the setup to someone who doesn't suffer RSI?

It is really very smooth so no RSI required. :) I highly recommend it although it does take some getting used to. The movement is as smooth as if not smoother than with wasd.
