I kinda fail to see the whole point of WAR having to sac HP and it being counterproductive to their output but DRK gets a way to get the effect of their HP spender without saccing HP and them going a bit lower in HP is actually productive.

Their general lifesteal is only up every 20s and is their only source of healing apart from Recup. Quietus is 15s and decoupled from TBN. And they also gain HP and MP from killing enemies recently plunged on and a regen for being in their Salt patch.

We already got an HP sac job, why another who does this half baked.
