You're going to do what you want to do and that's fine. But because this is a forum, I feel ok with sharing my opinion.
Like I said before, the reason this sorta works on other games (I've never heard of WoD games having FC's, so not sure how that applies here), is those games have such a momentous cast of possible FC's. With such a limited pool here, it just seems both silly and asking for ego-driven cliques.
The interview process doesn't change my opinion. This is the internet not only that, but these are games where people regularly pretend to be something their not constantly. If I can successfully pretend to be both the opposite gender, opposite sexual orientation and someone whose personality is in direct conflict with my own, why wouldn't I be able to convince you that I'm awesome, even though what I really want is the shiny badge of playing Varric or whomever else. If I get to play a FC, I'm automatically assumed by people who are familiar with the games to be important, or to be respected IC. It gives me a edge, regardless of where the stories go. I'll have a in, I won't have to work to develop a character to MAKE them important, I won't have to do the work to develop a backstory, or figure out my place in the world unlike everyone else who didn't get a chance early on to snatch up one of the coveted FC positions. People who come later after all the FC's are required to actually do the work, to make a effort that the people who just take an existing character didn't have to do.
Life might not be fair, but we like when things are fair and can limit unfairness by choosing not to partake in something, and that doesn't seem fair. Again, the games that succeed with FC are the ones like Transformers and Marvel. With countless FC's to choose from. There just isn't a pool here big enough.
