Better GW2 movement controls?
the problem with that is you still have to lift your fingers off from movement buttons when activating skills
But putting your hotkeys comfortably -- for you, as what is comfortable may differ from person to person, so I won’t claim where I have mine is optimal -- around your movement keys is a solid approach. You cannot move backwards and forwards at the same time, nor can you move left and right at the same time. So potentially you have a couple fingers on that hand that should be able to hit your hotkeys without disrupting your movement. Or, at least, disrupting it a minimal amount.
