The reasons why, could be anyone's guess. However, since it infers an accusation of 1he/1hb enforcers being overpowered in pvp; I'd like to go on record here by saying, that gank setups that have stuns and dimach/sneak combos CAN be done with almost all the weapon lines available. The obvious red-headed stepchild is 2hb, but 2hb is not meant to operate in PVP the same way.
