 But I doubt it would matter much in bom choice. Boosting the primary attack you do 0-0 times a second, will allways be more beneficial than boosting any attack you do once in 0 seconds. For the same reason 0wl/0f and 0f builds use a cleave bom and shield warriors usually a shield bash bom. I would strongly recommend using a rending slas bom for a bleed warrior. Rending slash bom does boost the bleed part iirc.
