Double tap to self cast?
I've been playing League for a few years now and one thing that's always bothered me. Champions who have abilities that can be either casted on allies or themselves can be kinda frustrating. Having to hover your champ in an intense situation is kinda frustrating, and having to change the way my hand is positioned on the keyboard to hover over alt makes things a little complicated.
That's why I propose we add double tapping to self cast an ability as a quality of life change. It's in essentially every other MOBA out there, including Heroes of Newerth. When HoN has a feature that you don't, you know there's a problem.
