Request for a Dark Knight rework/buff

I've played this game for 3 years now and only decided to post now due to the sad state of Dark Knight.
It's been my main since I first started in Shadowbringers and ever since then the job has just been considered to be the worst tank in the game, in Dawntrail especially.
Low damage, low survivability and overall just not as satisfying to play compared to the other tanks. A tank that deals a lot of damage? You have gunbreaker. A tank that's easy to play? Warrior. A tank with a lot of utility and defense? Paladin.
Dark Knight is none of these and overall just does what the other jobs do but worst.

Even if not a full fledged rework that would make the job more fun to play some potency buffs would be really needed. Specifically for the delirium combo to make up for the Blood weapon/Delirium problem.
For a rework it would be nice if Dark Knight fulfilled the niche of choosing between going full dps or full tank. Maybe GCDs with shared cooldowns that either granted damage reduction or damage dealt. Anything would be preferable to the state of DRK we have now.
I've always loved DRK due to it's fantasy, story and just the ability of using a big sword. It's what keeps me from not playing it anymore despite how bad it is.

Hoping for a brighter future for Dark Knight.

It's a survivability issue imo. Why do 3/4 tanks have good sustain and DRK has none? There's mitigation percentage issues as well that are nonsensical. They buffed the potencies of abilities....who cares. That's not what anyone was talking about. I'm never one to nerf, I just want drk to have the same sustained as current tanks and there's no reason it shouldn't.

It's in desperate need of a rework, yeah. Potency buffs aren't really going to fix the boring as hell burst downtime and complete and utter lack of job identity and mechanics.

DRK is fine regarding survivability, but it does have cracks that are beginning to show. There's multiple ways they could go about it. I just don't want the job to be even more homogenized because the defensive kit is one of the last things that's actually fun about the job.
