Something needs to be done to better prevent afks...

This is mainly me venting and I don't know where else to write this but seriously Riot, something more has to be done to prevent AFKs because 4 out of my last 5 games have had an afk player and I'm really f'n sick of it I don't know if you can just have an AI take over or have a drop in system or something but really, going 4v5 in any game mode is basically a loss especially if it happens at the very start. cause then one lane gets free farm unless someone like the jungler covers but they aren't set to lane or vice versa and it just leads to a snowball and loss

If anything I wish there was like that **other **game has where after 5 minutes if the afker hasn't returned then the game is not counted and those of us who don't like wasting time on a snowball loss can just leave and queue up again without having to wait 15-30 minutes
