Funkybot seems to use outdated safespot checking. I am probably 100% wrong with what I think it is. It'll spam found for a safe spot to move to when an elite or champion pack is found and stops doing everything else. My sc toon has died so many times from killable mobs when the bot is doing nothing other than looking for a safe spot to move to, while not actually moving at all. Trinity is much better at being useful more often.
That being said, funkybot seems to be a LOT better at resource management than Trinity. Trinity tandem spams cyclone strike until I have no spirit and at least 25% of the time won't use my primary to build spirit.
Both have their problems, but for HC, funkybot is much more dangerous.
