You can bind shift or alt + any other key as a second binding while your waiting if that helps e.g. q is fireball and shift q is magma and alt q is inferno.
Actually add a third button that needs to be bindable...left ctrl. So left-shift, alt and control are not bindable. lol. I thought you all played this game? It's alpha so I hope that was not intended and an oversight. Thanks for fixing ASAP!
