Brainstorming class abilities

By Garner, in Dark Heresy House Rules

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.

I can't see anyone ever wanting to play an Arbitrator because of that ability. There are just a lot of incorrect asumptions about what an Arbitrator actually does (in term of in game rules) for it ever to be useful. If you want definitive class abilities, go look at a Ascension. The relative balance and power level of Ascension abilities is all over the place, but those are the kind of rules that you should be trying to emulate.

I agree this ability isn't enough to attract some one to the class. I'd like to think of it as a start or some thing to sort of add some features. Arbitrators are often portrayed as Judge Dredd like so I thought giving them an ability that makes it easier for them to pull stunts you see in cop movies would be fun.

Not sure I want to pony up money so that I can make house rules but if I get the chance I'll give Ascension a look.

I titled the thread Brainstorming so we could come up with some stuff. Help me out with this Arbitrator ability? What do you think would help spruce up the class?

One idea you can lift from ascension is to give them one base skill and then one from a choice of three, so there is always some variation
