I said we are tied wie classes that have mobility without their mobility in mind. Aka patchwerk dps, where mobility isn't affecting output. The first part of my sentence was maybe a bit misleading, should've mentioned patchwekr dps to make it more clear.
Also, I never once said I wnated more mobility. I want compensation. That compensation doesn't need to affect our dps at all. Our output is pretty good right now on beta, asking for buffs in that state is something only mages can ask with a straight face.
I ask for something. That can be a solid selfheal, hell let it cost dps like DSi did. That can be stronger defensives (reasonable ibf cd, ams not being a joke, lower penalty on corpse shield or something else entirely). Yes that could also be mobility but as you said, its currently not part of the fantasy and therefore not a good fit. I would welcome trading Wraith Walk for the old Death's Advance but that is also hardly a mobility icnrease and more of functionality thing.
Personal favorite would be selfheal tbh. Selfheal is for me pretty iconic for the dk class. It was always there in some shape or form and subject to a lot changes but now they basically cut it, DS with being melee only, the huge cost and small heal makes it pretty unreliable and only useful for clutch moments and if you're not in melee range you cant yourself at all.
Lastly, if they wouldn't have nerfed Clawing Shadows into the ground I don't think I would've made the posts. Since then we would've a reasonable ranged filler, we could even AoE pretty well entirely from range, but they trashed that talent so we don't have that anymore without paying a significant amount of damage from the get go which CS won't bring back with its utility outside of extreme scenarios.
