Yo Riot, C'mon now.

Hey, my duo and I are extremely salty right now. Our fourth promo game, and an intentional afker is in our game, leaves at 5m, game goes on to about 26m, we lose. No loss forgiven? For 20m afk? Literally fucked our promo right in the ass, pardon my language if you please. I'm honestly concerned, because this has happened in two different seasons for us, for a total of 6-7 games of promo's if my memory serves. Why is there not a safeguard against this? Why is it that the enemy team gets a free win while we get fucked, and potentially dropped a rank because of it? Any response from anyone, community or otherwise is welcome. - This was posted in the wrong place so this is a repost, I just would like someone, even if its just a community manager or anything to see this and maybe just bring it up.
