Request: "Smartcast" for Ground AoEs

[Shougun]

I'd love this feature, but if I may add that it smartcasts when keypress is let go (so if you tapped the key it'd act exactly as you described) but if you held the key down you'd get the aoe aiming UI (and letting go then fires the spell off).

I can't remember if LoL's behaved this way but I know HotS (hero of the storm) does.
