One piece of advice I would personally give is to test your ability across multiple control schemes.
Some people use mouse and keyboard; some people use keyboard only; some people use a gamepad. Some people use simple controls, others use legacy. Mouse and Keyboard will have an easier time using abilities that require the mouse to aim them, while gamepad will have an easier time using abilities that require granular control over the character's core movement. In the same way that the thok may be too stiff to control for a gamepad user, something like the momentum flip can prove to be too sticky for a keyboard user.
As a result, it's important to make sure you are changing your control scheme regularly during testing so that you don't end up catering exclusively to one kind of setup.
