FO and Scum both suffer from a lack of a budget Ace. Look at the Resistance and Republic, for example: both have I5 pilots that are cheap for their ability (Tali, Rickie Olie...) If they had a cheap I6 Ace, it would open up the list building to have FO Ace + 3-4 Tie FO's. As to Scum, there isn't really a way to build a triple ace list or a 4-5 ship list with an ace. (I don't really count Fenn + three I1 fangs, since the lack of a bid almost precludes ace play with Fenn).
My 2 cents.
