Blood Weapon currently is how a DRK restores its MP pool when not tanking. Changing Dark Arts to absorbing hp instead makes it so Siphon Strike will continue to restore mp at no cost, I would imagine at a similar rate as using Dark Arts while getting mp back with Blood Weapon active.

I also am aware that losing hp as a tank is a BIG NO-NO. Which is why again, as I would imagine, this would be strictly for OT use leaving Blood weapon to be used freely while tanking and still have a dps increase. The hp loss would simply be fixed by tossing a regen on DRK, similar to BRD paean to prevent pacification for WAR at the end of berserk.

What do you guys think? I am totally open to discuss, I am curious to see what the player base thinks of this.
