Ah! You mean that thing that when a puk attacks you, Pugilist, the puk would simply attack you walking Through yourself?
Yeah, that's pretty bad. One solution would be to give the monsters an attack range animation that is between you and the monster.

For now, with the Puks, I just toogle the lock-on off, so when they do the taillash I can go behind it and not being injured. Also, that's a tactic for some Blindside!
