User blog comment:Lykrast/Hard bots ?/@comment-18521310-20130921091731

I've heart that riot did, in fact, create Advanced bots. Unfortunately, the map-awareness, teamwork, and reaction-time potential of an AI vastly out-matches that of any human. Supposedly, the top-teir pro teams at the time were invited to test the advanced bots and got smokes. So, riot decided not to release it.

Whether this is true or not, I'm not sure. I suppose I could google to find a red post stating this, but I'm at work and I'm lazy. It makes sense though. An AI could easily calculate exact damage dealt, taking into account cooldown timers, CC, armor, magic resist, etc. If that damage is enough to kill, it can then chain-cc and burst flawlessly. If it's not enough, then they don't try. Who would have fun playing against that?

Regardless, from an AI coding standpoint, it's pretty obvious that even the beginner bots have a very shackled AI. They miss skillshots and ability chains sometimes in ways that are clearly intentional.
