As the title suggests I think there should be an option for this, because it's unfair if the AFK is in your team and it's times easier for your enemies to win the game. If a remake is voted positive if your team has AFK, you would not suffer LP loss or even a demotion, because of some guy that had a blackout. And furthermore, for your enemies, that's free LP right there.
This is a team-based competitive game. Especially in high elo winning a 4v5 is almost impossible. Even if that was your jungler who forgot his smite. Don't get me wrong, but I prefer a noob, rather than an AFK.
I got myself to suggest this, because long story short I got demoted for this exact reason. It's unfair in so many ways. I'm not even mad, I'm just disappointed. A game that has this huge player base, I don't think I'm alone with this problem. And that's one more step in making the game more competitive friendly and not ruining your spirit.
So, what do you guys think?
