An Idea I Had For Irelia's VGU

What if Irelia's resource didn't regenerate normally, but would be regenerated when you attacked champions or killed minions? For instance, Irelia could have mostly ranged abilities to match her telekinetic blades, but melee range attacks. So the player would have to weave in and out of close range to regenerate their resource and to hit the enemy from a distance. Think a playstyle potentially similar to a combination of Jayce's and Lucian's: Change from short-range to mid/long-range (like Jayce) while weaving in attacks between abilities (like Lucian).
