a)Revisions - do you intend to change "your" models rather often? I see it as problematic if the model changes style from a different one very often cause it destroys continuity in my eyes. (it's still the same ship in RP you)
Sure imports were replaced with discover models, but why should discovery models without any major issues be replaced rather fast?
b) Fearless is AoM's model which doesn't have any major issues or looks very unfreelancer-ish, neither does it have any bugs by itself. So I don't think it can be replaced without talking to him or some "Igiss override".
