Shadow clone can stay but needs to feed off MP for DRK to have two burst windows and one they can open up with at the beginning of the fight (Don't give me another WAR hand me down with infuriate to go straight into darkness combo). I would have shadow plunge straight into combat and avoid the 4 seconds of graphic before it starts attacking like now.

Soul survivor will come back as a trait - When "blood shield" or TBN bust hp value of the shield is reimbursed (numbers again can be tweaked). May be OP but DRK needs more passive healing on its abilities due to its normal healing being locked behind combos and not on demand like other tanks.

LD, ugh. If I had it my way I would flip things around. Instead of doing the healing on the back end where no one really knows exactly where they are at on the way to max HP. I would give the DRK an empowered shadow of inner darkness (would be an easy graphic to pick up on for healers) which we already have a taste of with the current shadow. I have in mind a black and reddish/purplish shadow growing out for the players body to x2 their size. The inner darkness would empower the dark knights HP pool to double or triple its normal value (hard for me to say since I don't know what the current numbers are for the heaviest tank busters in current content and no one does for the future). Healers would have the first 10 seconds before the TB to throw up heals/regens/bene to bump that pool up as high as they can get it before the hits. The real fun would be adding TBN on top of that fully extended HP bar for a massive shield. The downside would be if you die then you die - no safety net at 1 hp. It would retain some identity and allow healers to see what they are up against. (might be difficult to get the math right when you throw in all the variables but it could work out and man that would be cool).

The above might be ungodly OP in a dungeon with bene but, its just an idea after all.

If SE wants to keep LD as is then just give bene as a role action. I know some will hate me for saying it but LD is a healer CD clearly meant to go alongside with Bene. LD is designed around that 10 sec invul window so give ALL the healers some control to make that full invul window happen reliably.

The reason for so many passive heals on this build is due to no on demand heals like other tank classes. This in my opinion is the one of the biggest downsides of the shadowbringers build.

I know I probably missed an ability somewhere in there but it's a framework. There is room to tweak CD timers and potencies but I feel like that is a DRK design that pays some homage to versions that came before it and is unique as well.

What do you want to see for the future of DRK?
