OW is def nerfed in PvP. Between lvls, i think, 85-99 ow will drain about 2400+ life from monsters. In pvp, it drains maybe 500-600. Dont know the exact amount but never-the-less, its still very effective and worth using.
Deadly strike works the same as critical strike. Both do double damage in pvp.
Crushing Blow is nerfed in pvp.
here is a copy/pastes to with what u are looking for
