Wasn't it supposed to increase your stats too? I recall the description saying it would also give a stat increase. I'd imagine that either means an increase to Strength and Discipline, making your abilities recharge much faster, like having the Catapult PvE modifier active, or an increase to Armor, Recovery, and Agility. I honestly hope it's the former, not just the latter. That would kinda suck, and not really make it worth using.
