I really like where the Imperial Firespray is at currently. Sure, the new Scum Firesprays are better in many ways, but that ship is basically the poster child for the Scum and Villainy faction. After all the faction symbol comes from the shoulder patch on the faction's most notorious pilot -- the best pilot of the Firespray, Boba Fett (I'm using PS as a measure of "best").
But even though the Scum version has more options, the Imperial one isn't bad. The best part about the Imperial Firespray, in my opinion, is the Bounty Hunter. PS 3 and 6 hull/4shields for 33 points? That doesn't seem awful. It's the most points-efficient way to get the Firespray into any squad. To me, it seems fitting that the Imperial Navy is the faction that can get these lowlife, generic bounty hunters for the cheapest price. I wouldn't want to see them removed from the Empire, but I don't really see the need to buff them, either.
