Arcade most difficult AI to easy

Vihollinen

I usually play team matches with all default settings other than AI on the hardest setting and 250 kill limit. Even with the AI at that level, I get an average 50 kills if I never play a hero, and over 100 kills when I play with a hero because the AI don't single out the heroes. (at least in my experience) For those of us that play arcade and occasionally want a challenge, these AI don't cut it. They just run directly at you, and use absolutely no tactics. I don't know exactly how I would fix this, but if anyone else has any ideas fire away
