TFT is nearly unplayable on the PBE due to constantly afk AI

I thought the AI was buggy on live, but that doesn't even compare to the PBE right now. Multiple champs will constantly go completely afk and allow the enemies to destroy them and win for free. It's happened to both myself and various other people in my games.

If Riot wants us to be able to review their new features before it goes live, they need to fix the bugs with AI asap.
