I was referring to the FCR, actually. MR is basically what I'd subsume under the loose term "rebel faction". Those require an FCR in my mind, now that such a thing exists. As far as I know, the FCR existed already when you applied, so it wouldn't be a retroactive decision to argue the way I do. This boils down to the Outcast ID not being the right choice for you, as far as I can say.
If you want my opinion as a player, you should wait a month and then apply using the Freelancer or Pirate ID. Then you can request your official faction ID to have the same lines as the Outcast ID.
