Yeah, if the maul proc now follows the rules, then I think it's only fair to make Samael and Slag to follow the same rules. It's not fun dancing around literally like a fool to a team of 4 Samael's or Slags in PVP. "Panic" is still a form of stun, just that has a fancier name!
I hope there's some plan in place to make warriors able to kill rogues. As it stands, warriors are going to become the most rare class if they can't kill.
