So one of my buddies is convinced that the only unique roles in the game are the Sororita, Psyker, and Tech Priest and that every Guardsman, Scum, Arbitrator, Assassin, Priest, and Adept is essentially just a very slightly different take on the other guy.
While I don't entirely agree I thought it might be interesting to add specific perks to each of these guys to sort of back up their class identity and give them a sort of "special power" like the Sororita, Psykers, and Tech Priests have. This is just for brain storming.
Here's an example of what I'm looking at-
Arbitrator
Surprise Entry
-Once per encounter (as defined by the game master) the Arbitrator can kick open any man sized door or entry and immediately enter the room taking one half action.
Special note: This ability is not intended to kick open elevator lift doors and other doors that would not normally "kick in". This ability can be used in cnjuction with breaching charges or slicing.
This ability is to reflect what you see in the movies. The coppers can seemingly kick down any door in a single blow and then suddenly there's a shoot out.
