What issues? You have like infinite mitigation with the blackest night and after every blackest night you get to smack the boss for 650 potency atk. If anything, it is the best main tank atm. I absolutely love it. People just hate on it because it's not as complex to play as before since you just manage mp and spam dark arts. But I love the class. It has that badass look and it's just...dark. PLD and WAR look meh.
