Certain Paladin Virtue and Warrior spec skills

Thought I had logged it but I guess not. Paladin: Has the virtue that "senses an attack" and strikes first (dont know what it is called) Warrior: Axe/pole spec, Situation: Attempted to pincer the paladin while wielding a polearm (stupid yes I know). Instead of an echo saying "You must wield two axes to perform this attack" it treated it as a normal murder @target. I got hit for three massacres/mangles and the paladin did not yell the "hack me to pieces yell"
