Dark Kight again, i know there are other post but lets push it

Yes, because TBN is an overrated tool that has been used as a crutch to keep DRK in the dirt for far too long and it was a problem in EW that people didn't mind because it did significantly more damage but TBN has never had the uptime everyone pretends it does and it's time we stop acting like it has any place holding DRK defensives back just because it can be used every 15s in dungeons, when realistically in raid content it will only be used once every minute due to the MP nerfs and how it effects your DPS to need to use it twice. Its uptime rate is now significantly lower than it was before and its usecase is even smaller since you want to make sure you only use 1.

TBN has been bad for years but the MP changes make it's cooldown even less significant and giving Dark Mind the Addle treatment will not even begin to compensate for the objectively lower Mitigation numbers even based on magic damage because of how bad Oblation and TBN are designed to be. There is no reason for two bad skills to exist when they can merge and become one decent skill together.

Again, your suggestion and borderline personal vendetta with these skills is that they are too weak therefore they need to be merged/reworked, but your suggestion to merge them is hot garbage and solves nothing about the mitigation budget. The HP shield is completely unchanged and now it is less flexible to be used, with a CD higher than Holy Sheltron / Bloodwhetting / Heart of Corundum for no good reason. It is a net nerf, both in practice and in potential. You can personally space out Oblation in 30s intervals and have that go three times if you space it out that way - and can choose to not pair it with TBN because you don't need to all the time and can toss it to a teammate (either of them). Your whole TBN suggestion is complete and utter whack and you have yet to provide what enhancements would even be available if you broke it. I can use these skills together on my own without this shitty merge, at my own discretion.

And at that point, just introduce Dark Arts as an actual action for mitigation enhancement and don't do this roundabout delayed mitigation enhancement if you need mitigation NOW AND NOT LATER.

The MP changes are bad in general and isn't an issue for TBN alone, but even with that in mind you can STILL spend 6000 MP on TBN in a short time frame if you pool it that way, making the cooldown not irrelevant. A good example for that recently is Mountain Fire from EX1, allowing you to shield both the first and the third hit for your turn. In Abyssos you could double TBN the dot busters to cover a fair bit of damage without heals. Your suggestion would just make this objectively worse from a mitigation standpoint.

I gave three potential suggestions for Dark Mind, of which you only addressed the bare minimum one, I could even give you a fourth one - readding Dark Dance which is basically just a physical copy of Dark Mind and shares a CD. The goal with that change was to provide additional mitigation in predominantly physical damage environments which is most dungeons and a fair share of raid fights (P11S if we discount the invulned Dike busters, P10S Harrowing Hell, DSR Heavenly Heel + Ascalon's Might, etc.).

I also suggested changes to Oblation in favour of sustain, which you completely ignored. You also mention "how it affects our DPS to need to use it twice", like do you have actual numbers for this? What would the total DPS loss amount to if you'd favour TBN breaks rather than pooling 5 EoS in raid buff windows?

Mind you, I have played DRK throughout the raid tiers since Stormblood 4.3 onward - and not once have I thought that my mitigation was weak, at most I had wished Dark Mind could be at least half-usable on physical damage. I have done many savage tiers when relevant and I do not shy from Ultimates, many allowing me to make use of the 15s CD quite handsomely.

I could almost forgive it if TBN was made so utterly bland like you suggested and interacted in zero ways with our damage (MP), if you'd at least up the numbers of the mitigation you so decry being inferior to other tanks, because double the CD for the HP shield (5s over other tank short CDs) and barely a gain in Oblation uptime (if used on cooldown) is not it chief.
