I hope that PfP table still affect the "body" of the Drukhari, and the weapons.
For shooting improvments I would like to see new weaponry, and just straight buffs on weapons.
But PfP should effect the bio of the Drukhari, his physical skills. Like Vampires-With-Guns, where the blood is the pain.
Maybe we can argue about +1 WS or some reroll ability, but no better Ap on guns or similar. Imho.
