Changes based on DRK's thematic approach to combat

[Nedkel]

Blood weapon usable in grit would be just enough.

You cant just out of nowhere give an infinite amount of MP to the job that could sustain itself so hard. It will make DRK unkillable with Abyssal drain and TBN usable all the time.
The only thing that hold back DRK is his poor resource management compare to the cost of the skills, it already is not that bad on lvl 70 with quietus, delirium and etc. I am even afraid blood weapon would be too much at this point.

Dark passenger should have its potency increased to 140 (along with DA damage to 280), nothing more, that would be enough to balance it out, not being weakened in any way, because you will make low lvls drk to suffer even harder than they do now. And the salted earth is not a bad spell, it generates blood gauge and does dps every 3 sec to everything in the aoe, the tooltip on it is broken.

Also you cant really give a burst damage to the job that would have so big sustained dps, it would be overpowered.
Using DA on bloodspiller is not necessity, it just adds 140 potency same with other weaponskills. It still does its job with 400 base potency and 475 when in grit.
Change would be cool, but again, pair that with the blood weapon, blood price and etc you will end up with DRK having more dps than current state warrior, when he will be allowed to pull out 1k potency combo all the time with additional abilities like quietus, bloodspiller and etc.
