If anything, improvements to Living Dead / Holmgang would be QoL for informal party configurations, solo, and misc game content (MSQ solo instances, Hunts, Treasure Maps, etc.. Aqueous, Hall of Dead inc), nothing to do with Raids, like stated, if your static is coordinated, holm/ld are of small consequence, right?
Might as plug my LD/Holm ideas while I'm here,
Holmgang
Add Additional Effects to Fell Cleave, Decimate, Inner Beast, and Steel Cyclone while Holmgang's active. These skills consumes the Holmgang buff/debuff.
Fell Cleave: Guaranteed Crit chance (enemy has to be suffering from *your Holmgang debuff), effect fades on use
Decimate: +30% Crit chance (you have to be under the effect of Holmgang's debuff), effect fades on use
Inner Beast: +30% Crit chance, 1.5x Health return modifier (enemy has to be suffering from *your Holmgang debuff), effect fades on use
Steel Cylcone: +20% Crit chance, enemies hit with criticals are stunned, and 100% of damage dealt is returned as HP (you have to be under the effect of Holmgang's debuff), effect fades on use
Living Dead
Instead of switching to the Walking Dead debuff at 1 HP, DRK's HP pool simply goes negative. Easier on the eyes for healers, and changes the 'MP-sponge' aspect of Living Dead to a dynamic metric.
Dynamic being that amount of Heals needed to survive Living Dead is determined by the amount of damage received to begin with. (Otherwise, the skill is exactly as it was). Solo fighting Forneus and he clips you by just a hair after Chrysabyss (which reduces your HP to 10% of max), well instead of being Doom'd by a friggin ARR mob and it's unavoidable mechanic, you still have a fighting chance to make out okay.
If Another Victim's duration was reduced to 10 seconds, I don't think the PVP adjustment to Sole Survivor would have been completely implausible in PVE. Trick Attack is what exactly? a 2% raid-wide DPS increase, generously? Cut that in half, and that's 'game-breaking' utility for a tank? I'm sure there are plenty of progression groups who would have appreciated the addition.
Not that I'm displeased with the buff as it is, being PVP specific. It'll get me to test out DRK in PVP again,
only took ~10 months.
