I get the concern where having FCs as playable characters goes. I've been on games where that was most definitely a problem and it does suck when your character is forced to be in the background while the FCs are given the spotlight. But I do think that the staff is trying to not let them be like that. Case in point, they let me app a character who is a high ranking Imperial officer, a role that is going to require her to be out there and kind of in a spotlight of her own. I really don't think that they would have allowed me to do that if they were wanting all the attention for their own (not said to brag, I'm only bringing up my character to hopefully try an alleviate some of the concern people have).
Now, that said, I do hope staff will be willing to shut down any attention/RP/scene hogging people playing FCs might attempt, regardless of if they're played by staff or not.
