I still agree and think that you are somewhat correct. Nevertheless: the pros are training 5v5 exclusively. 1v1 is a just for fun gamemode, the money is earned in the 5v5 tournaments.

I am not saying the bot should be able to play 5v5, I am saying that he ist trained to play this one very specific 1v1 scenario. He is doing really well with that, but as soon as you pick a different hero, the bot will struggle.
