Yeah, I wrote nearly the entire thing, and it's definitely a work in progress.
Now, we do have the Oath that every staffer signed... I believe that was posted? If not, I'll ask Tah or Gulp to post it. It covers stuff like that. So, at least, all the staffers are promising to behave.
I'm not going to be playing a real PC. So, at least, I won't be able to steer things one way or another. But I do have friends and I can see that you want to avoid the bias.
The bit about favoritism in the oath is: I will show no favoritism; this includes, but is not limited to other Staff members, characters of your buddies, and potentially the factions you run. If there is a direct conflict of interest, such as a Storyteller being asked to run a Rogue Squadron vs. Sith battle in which his Rogue Squadron character is involved, I will immediately ask another available Staff member to take over, or if it's not possible, I will refuse to participate as a Staff member and give an excuse
A few things.
1) I think the oath covers the "do not abuse your position." And so I don't think we need a huge list of things not to do in the handbook itself. I am very much about the SPIRIT of the law. It's not "okay" to use your bias for a friend of a friend just because they're not your direct friend and thus you found a "loophole" in the rule.
2) Templates cover a LOT of stuff that STs do. And if a ST isn't doing something via the template, that's going to raise a red flag for both PCs (who see the templates) and staff. So that's a way to CATCH it.
3) We're documenting everything staff does. Decisions, etc. If a staffer is making a ruling and not documenting, that's wrong and will get them in big trouble and the decision will get reviewed. If they ARE documenting and others on staff are seeing this trend always to the same guy winning in situations NOT covered by +checks, etc (ie: it's a situation where a ST is making a decision, and it's the same ST with the same PC every time) then that's also a red flag.
Abuse will happen. But we're going to be good about catching it and PUNISHING it. You will not be able to be a staffer and abuse your position on DH2.
