Unfair 4v5 Ranked Games...

I freaking hate how there's an afk or a dc on your team in a RANKED GAME. I keep losing a lot of ranked games due to a 4v5. RANKED SHOULD BE A FAIR 5V5 GAME. In my opinion, I think that Riot should make it where your ranked game won't be a loss and won't count as anything if you lose the game with an afk on your team. Many people don't even have the chance to climb divisions/ranks because of afks in their team in a lot of games.
