Can we make Runes a post game reward as well as purchasable?

Probably a horrible idea at the end of the day, but what if every win/loss also gave a single rune to equip? Or if certain runes became level up rewards, etc etc.

Runes in general are just a pain for newer players and older players who don't spend a ton of time on the game. Can we please do something instead of just twiddling our thumbs and hoping an idea comes up?
