With respect to Warrior AA Tactical Mastery:
"Studying one's opponent for weaknesses provides the Warrior with the ability to pierce through advanced defenses. Each rank of this ability grants an increasing chance of bypassing an opponent's special defenses, such as dodge, block, parry, and riposte. You may train in this ability at or after levels 61, 63, and 65."
I've never once landed a melee hit through enrage or on an auto-riposte mob (except for kick which strangely almost always goes through enrage/riposte). Is this just a feature of the way enrage/auto-riposte mobs work or does this AA maybe not work to bypass the defenses of mobs?
