Riot, please fix the afk system. / Rant about yolo que

I'm struggling to go up only to be back down from where I am. I don't really understand how easily people including me throw and never EVER group. This costed the game so many times.

Also, my friend decided to afk in a ranked and never show up along with a guy that kept bitching about being DDOSED/Drophacked in game and kept yelling at us to report the enemy team.

If they never show up, is it possible to add a function that replaces the player entirely? It's not complicated since they never even purchased items, etc.

Unrelated: Just played with a scripter. It was a disaster. I called him/her out and he/she fully admitted to scripting and then resorted to calling me a butthurt noob for it. Ayy lmao, we lost that game since we didn't really win fights nor did we group. "I have many accounts, they're like $5 nerd"
