Should Dark Arts Come Back in 6.0? If so, What Should the Skill Do?

[currentlemon]

Hey, it's good to see that my post came back up. My opinion on Dark Arts hasn't changed. The skill needs to come back in 6.0. What has changed though is my opinions on what the skill should do. I don't think it should use the blood gauge. Either it becomes an MP spender that competes with Edge/Flood of Darkness or saps the DRK's health slightly.

Either it becomes an MP spender that competes with Edge/Flood of Darkness or saps the DRK's health slightly.

Most of my old Dark Arts remaster ideas have hit either the "but that would be a damage loss" wall, or the "but that would be a liability" wall, so I am not certain at this point, how to design Dark Arts... Other than a boring or dull design that would kill the point of my attempts to re-design/re-master the ability... while on the other scale, my ideas also hits the "lazy and simple preferred" wall.
A (common?) issue brought up against if old Dark Arts were to return, is that some people express(ed) that it should not be a liability... (A lot of/some?) Dark Knight players would prefer that Dark Knight is "just as easy" and requires just as little effort, as the other tanks, while Dark Knight actions have to be equal to the other tanks, without Dark Arts...

so.. like, Dark Arts is not allowed to have offensive or defensive effects, under those limitations, because other tanks do not need to use a additional ability, for their defensive strength and damage potential to be as good as other tanks, and Dark Arts is also not allowed to cost MP or other resource(s), like BlackBlood gauge, under those limitations; as (a lot of/some?) Dark Knights do not want Dark Arts to be a liability or a "damage loss", or a necessity that the Dark Knight is reliant on(SB DA spam = ew.)...
to re-design Dark Arts under these guidelines has proven difficult, as a Dark Arts like this would be.. not much of interest, and little akin to the iconic and fun old HW Dark Arts... hie, I am not certain how to re-design Dark Arts...

My #1 most lazy idea at the moment, that may fit the bill, would be if Dark Arts is a oGCD ability with a CD, no resource cost, and its effect only slightly alters the effect of a action, changes what a action does, but this change has to fit every afore-mentioned guideline, or adds self-healing effects to actions; while Dark Arts itself could be either a short duration "all GCDs/oGCDs used in its duration" passive buff, or the action is a "stacks"-style passive buff that has you spend its limited stacks/uses at leisure.
