Idea to Help with AFKs in Normals

Alright, I know this isn't a perfect solution and it's probably been mentioned before, but hey I really like the idea. HOTS has a system where if someone AFKs or DCs (for whatever reason) an AI will take control of the missing hero. This means that a computer will control the dc'd champion in league allowing for both sides to have 5 champions. Obviously, this is pretty easily abused. Enemies could focus the bot, people could alter a bot's programming, bots can't communicate, ect. That's why I think this system should only be implemented in nonranked games (including aram). That'll keep normal games feeling more fair and fun so that one person leaving doesn't automatically ruin a game (dcing is going to happen eventually).

(Not to mention, depending on the situation, the bot could perform better than a dc'd team mate. A team mate that rage quits has the benefit of not tilting and being quiet.)
