That's why I gave his ult no charge time, to make up for the slowness of his charging. I mostly centered the idea of preparing yourself before fights, hence why he has to stand still to regain runic energy and to charge his abilities. Oh and yeah, the abilities stack, otherwise you would have to choose between dealing damage, initiating or staying alive. The ult is basically so that in a team fight he can be at least decent after he's used his other abilities. However I do see where you are coming from.
