Dark Knight: Magic Resistance debuff idea

Hi fellow Tanks :)

i apologize in advance for my english,i'll try my best. ^^

So, i know currently we have TONS of Dark Knight revamp post and... sandly this is another one. But this proposal has been around in my head for a while.

-Delirium:
With a MnK in the party is a pretty useless skill. Change it to a magical resistance down debuff. Something like 5% to help the Dark knight utility to fit in the party. The debuff can't stack with foe ballad (otherwise it will be too powerfull) not sure about the Hypercharged effect of Mch, this needs developer test.

-Reprisal
Reprisal can stay as it is, just add a possibility to use it without the proc if you are under the effect of Dark Arts. Obv Dark Arts fade upon execution. This change will cover the lost of Delirium effect in non-mnk-party and help the DrK to be in pair with the warrior debuff. If the effect with Storm path is too strong, just make that it lower the potency if stacked up with it.

-Dark Arts
The DA reprisal will cost tons of MP, less souleater buffed less damage. To fix it i wonder if we can make the DA buffed attack as also magic attack. in this way it will provide a little buff from Delirium and make the Dark knight a kind of magic tank. (well... not so much but more on pair with the lore and the ability mood)

Carve and Spit
Add a little regene of TP if you are using it outside of Dark Arts.

Conclusion
With this changes the DrK will have more utility for the party on the same route of the other Tanks skill ( Pld have huge party mitigation and help skill now, Warrior still prove the two Storm skill debuff). Moreover, in that way the Drk will have less conflictual skill (delirium with monk), reliance on other job (War, Nin) and less situation skill (reprisal).

If you have readed so far, Thank you for your time ^^
