I go with the mindset that 90% of my games will have an afk.
Remember, this is a great game based on 5v5s..or it used to be. A game with no system in place to fix 4v5s and the only solution is to defend for 20-60 mins or ff it.
I would love for a Riot response on how great of an experience it is. I mean who am I to ask oh glorious Riot for a detailed response on what a better solution there can be.
