Afk's

Hi.

I have been playing ranked games quite a bit lately and I've noticed the amount of AFK's and this is throughout bronze to diamond is insanely high. Like probably in my last 3 games on multiple accounts I've had 2/3 Afk's which is crazy because different accounts right? So I was thinking whether Riot could implement tighter restrictions on AFK's in ranked because it's really tilting. Maybe a ranked cooldown for a couple of days or something?

Let me know what you guys think (because I know its probably a stupid idea)
