Is there any chance we could make Zilean's Q targeted *when used on allies*?

The ability to put a bomb on an ally and have them blow up was always kind of an important Zilean thing. It's still possible, but having to land a skillshot that's designed to be dodged on an ally who doesn't necessarily know exactly what you're planning at any given moment is incredibly painful to do.

Is there any chance it could be changed so that it auto-targets allies when you cast it while mousing directly over them, while maintaining it's skillshot nature when used anywhere else? It'd save a lot of painful moments where it feels like something would've worked but your ally accidentally moved too fast/too slow/flashed/whatever.
