It's okay out of 10. I'm still playing it, so it's better than MCH I guess. A couple of problems I've run into while playing it, though:

-Getting 5 GCDs under Blood Weapon is far harder than it should be, and I think that's because it's slightly less than 10 seconds for... some reason. It's really irritating.
-Scourge as a combo ender please, I'd like to have some minor variety while I wait on my buttons outside of 1-2-3.
-Someone here suggested out a cooldown reduction on Abyssal Drain, I'd like that too.
-Dark Mind should be put back to 30%, if we're going to get a specialized tool, it should better than other general-use tank mitigation for that specific use case. A lower cooldown isn't really enough to make it better.
-Living Dead has exactly one scenario where it is the best Invulnerability; when you're chilling in voice with a WHM with Bene up that knows how LD works. Outside of this, the skill NEVER realises its full potential, and consequently becomes the worst.
-TBN needs something to make the admittedly minor risk of it not popping (it's very easy to not be frivolous with it, come on guys) with a reward that isn't "I don't eat shit" when the negative is "goodbye 500 potency". There are some cases I'd rather just eat shit and get the Edge out right now, but it really looks like it's been painted into some sort of corner where it's hard to implement any kind of meaningful reward to it without some unforeseen reaction takes place.

Overall damage should be a bit higher. People keep saying "ohh but it's only 4% it's literally nothing" in regards to the disparity between tank damage, but both DRK and WAR have been consistently doing less damage than Mr. Look at all my fucking utility. It's 4% too much. PLD should struggle to take 3rd place from DRK, and I only make that distinction purely because of how defensively strong TBN is. The current standing of GNB>>PLD>>WAR>DRK is not fine. The distinction would be far easier to detect if we were talking about DPS, so let me use that kind of analogy;

The Red Mage is consistently outperforming the Monk and the Dragoon in terms of damage.
