My only major complaint with Dark Knight is Delirium being War-ified... Hate that change, it's not satisfying to do in the slightest... Press a button and spam the same move... Inner Release gets away with it because it becomes satisfying to have 100% Crit/Direct Hit rate, plus the animation is a hoot... Delirium lacks all of that flair...

Other than that, my only complain is pretty much universal across all tanks; There is a distinct lack of variety in skills. Warrior bucks the trend somewhat, but when Sentinel/Shadow Wall/Nebula are literally carbon copies? Intervene/Plunge/Rough Divide are literally carbon copies? That's a problem IMO. On the flip side, the Hallowed Ground skills just have variety for the sake of variety, with essentially no interesting flair added to justify the negative effects Living Dead/Superbolide incur. Give Gunbreaker something for dumping 99.9% of its HP. Give Dark Knight something while suffering Walking Dead (I'd actually slap the current Delirium effect on there, personally).
