I thought they intended all shared trees (Assualt) to be the PvP tree. If you look at the talents they seem to be very PvP based (holds, breakouts, etc).
I'm not sure it is really that bad that you have to use a 10m power to get the CD lifted on HIB. Heck, isn't most of the high damage to ammo tools in the 10m range anyway? (excluding HIB).
I'm not into PvP (cause I suck at it) but I made a PvE DPS Hybrid build focusing on HIB procing:
