Please don't wait until season 8 to update runes.
I drastically think this could reduce people's "Elo hell" and flush out a huge player base of actually skilled players that just don't put effort into rune pages or masteries and they often plain just don't pay attention, often costing their team. This would fix so many issues and like the 10ban system has so far imo. I don't think you should wait till season 8 to do this. Maybe I'm alone in this but what does everyone else think?
(Besides so many players are good but just don't BUY runes for every champ. NEWS FLASH every champ needs it's own rune's most likely)
