Should Riot actually start giving a flying f*** about akfs?

I'm so tired to losing ranked games to people akfing. Especially those who afk because they get told that they did something wrong and are given criticism and they're all like "I'm not going to listen, I'm going to go afk **** you guys." I know this game is known as "League of Children" but seriously can we actually try to change this? I love this game, but just hate the community. There needs to be more sever punishment for people who afk, especially the ranked games. Why should we be punished because someone can't be mature enough to listen? I actually contacted riot about this and they told me to "Create a discussion." So as of now, they really don't care and this is something that they should actually put more thought into. DoTA has ways to help players if a teammate d/c. So why can't we?
