It honestly sounds like you just want DRK to play like a DPS class man xD

The idea of crossing over KF has crossed my mind, however a tank getting B4B is just a bad idea. Let them have KF and Invigorate while blocking off B4B and I'm all for it haha.

Hell a simpler fix would be to allow reprisal to be usable while blood weapon is active (while keeping its parry proc as well) that way they can be an outstanding OT while remaining unchanged and can keep foresight when they become MT.
