Not the usual "bring back Scourge / old Delirium", buff xy, rework everything, none of that. Just a simple thing about Grit.

Grit - 1800MP
Instant-cast (ogcd), 10s recast timer
Replaces Blood Weapon with Blood Price while under the effect of Grit.

Basically, make it ogcd so you can weave in / out of it easier in between skills and do a Defiance-Deliverance thing for Bloodweapon and Bloodprice the same way WAR does it with stuff like Inner Beast <-> Fell Cleave, Steel Cyclone <-> Decimate and so on. At very least that if we don't get Blood Price outside of Grit back so we can save ourselves a hotbar slot.

While it doesn't fix the issues DRKs have, it would be a nice QoL change for DRKs that play despite the handicap but also utilize Grit somewhere.
