By this logic, we should've removed the BHG battleships. There was plenty of complaining about them back in 4.84!
Come on, I'm sick of saying this already. Changing the rules will not fix the problem. It won't get rid of the gunships (they'll just change IDs), it won't make them RP, it won't fix a damn thing.
As for the RP... having played other space games, I'm increasingly wondering about the logistics of a lone fighter being able to go all over the place like they can here; logically, it'd be freighters, transports, and gunships making most of these trips, fighters would have to stop for refuelling and supplies far more frequently. Perhaps too frequently for such a trip to be reasonable.
But, I'm sure there's some background info that hand-waves the problem away rather than actually explaining how it works. The Daam K'Vosh make this kind of "explanation" so much easier.
