Because the first two matches were so lopsided, the bot lineup was selected by twitch chat + audience members. We drafted them a pretty terrible lineup, and from the start the bots estimated their chance of winning to be about 2.9%.
When I think of AI, I think of something crawling its way out of purposefully adversarial situations such as this one. I would have loved to see optimal play from 5 wacky heroes.
I just have this suspicion that that wasn't optimal for that team comp.
But of course the matchup itself is a thing.
