I think that it would be especially cool to see force jump done with improving animations as you level up. I think that force jump attack should be a special option, rather than just clicking the normal attack, when you're in range. That would make things alot less confusing and prevent accidental force jumps when the PC auto targets someone. I have no qualms with the fact that you force jump (and attack while doing it), land, wait for your next action, and then attack. Seems reasonable to me.
