Critical hit WS's are still powerful in and out, For the most part Raging Rush > King's Justice (outside of 2hour). Evisceration > Dancing Edge (most of the time. its close but with the right gear theres no question). Rampage > Everything else. Vorpal Blade > Swift/Etc, Drakes > Penta
Some of those are bad examples but i think you see my point

. While you guys dont need a Crit WS at all, It would be a nice addition. Could simply adjust Cross Reaper or Guillo to be crit, Given their fTP it wouldn't be any more broken than Drakesbane.
