In reply to jsbots: [The default settings should already have heuristic logic, if that what you meant by "safety". You can tweak them a little to make more unique.]
Yes, I suppose Blizzard uses a detection system that tries to identify non-human patterns in character movements. If the program can mimic movements more akin to those a human would make, that would be quite safe, I assume. I'm speaking from a place of limited knowledge.
