Heh. Sorry for breaking into. Let me tell of my example. I had (still have) outcast mercenary character. Wrote a short story for him, and then played it in-game, came to Alpha on bounty hunter ship seeking shelter from former guild mates (a set up in story took place). After some roleplay done, doing missions and slowly gaining trust I switched over to Sabre and was done with it. Character was set up and assisted both 101st and RoS several times as a mercenary. Everything was explained, all being written down, played to the letter and nobody it seems had a problem with that. Why people can't do the same then instead of going completely odd ways and raising unnecessary controversy on forums?
Mercenary ID is not carte blanche to use whatever you desire sticking to whichever side. Not at all. It's quite restricted one when played properly, problem being is that it requires self-control and understanding of boundaries as to where your roleplay, equipment and ship choice can go and where they cannot.
