So I'm playing Unclean.  I've got level 3 Diseased Claws, and Level 3 Inner Beast.  I'm running 30% faster, and I'm slowing down something I would hit.

An enemy healer goes running up to me, so I take a swipe at it and hit it for 192.  It goes running past me and I swing again, for 212.  It keeps running past me rather than stopping to fight me(!), so Unclean takes off after him.  Somehow, I'm outrun by this thing.  It *should* be slowed down from two hits, and I should be running fast, but it clean gets away from me.

Next up is Rock.  He comes up to me and does his hammer blow, ow.  I activate my berserker rage and dig in to him, blows of 800+.  After a few moments, he decides to turn and flee.  Unclean gives chase ... sort of.  Unclean take a step towards him and pause for a moment in thought.  Rock is running straight away.  Unclean takes another halting step or two, then stops and looks around, then takes another step.  Rock is now within his defenses.

I shoot my venom at him, but he sucks down a healing potion.  I right-click on him and my character charges up to him, but he turns to run again and Unclean stops and looks around before giving chase.  Meanwhile, I'm being beat upon by towers, and Rock is sucking down another potion.

So .. is this a pathing thing, or is Unclean stupid?  I've had Rock at 2% hit points repeatedly, but somehow Unclean is Uninterested in delivering the final blow, so I just sit there watching him get away.
