An Idea for solving Afk/Leavers in Ranked.

What if (bear with me here) a single Leave/afk in ranked, resulted in an instant 1 day ban from ranked. Now this may seem strict, but it would prevent trolls from ruining a multitude of matches a day, while people that accidentally get dc'd due to some unfortunate event; can just wait until the next day to play ranked. Now this isn't a perfect solution, but it would solve some issues.

I mean if you aren't going to go into ranked serious, then you shouldn't even go into it at all.
