I left channeling pylon checked, I use 2.13.17 trinity. Yes sometimes the bot will spaz out for a second, but for the most part he will dash around like a mad man BUT he still kills just fine(using ulianas SSS). I only noticed maybe once on a very bad map to begin with that it had an issure with channeling pylon and even then it depends if it gets itself caught in a bad area or not. Dash can leap over walls etc most of the time.
