I'm leveling up a new account and playing Coop vs AI. I have at least one intentionally feeding bot with Cleanse/Exhaust and Corrupting potion every game. In fact, I dodged one game full of them and the next game had 3. Even as a Gold+ player, I could not win playing Maokai JG because these 3 bots on our team actually die 10x+ without doing anything. It literally was 2v5 vs Intermediate bots.
I can only imagine how horribly boring, depressing and straight punishing it is for new players evaluating the game. It's literally the worst experience I've ever had playing a "game". It's not even a tiny bit fun. It's arduously boring and lacks any redeeming qualities. I'm amazed LoL gets any new players at all if they have to put up with such BS. It's actively anti-fun playing that game mode.
