Well the current stats on this are garbage so I don't use any, its also limited to Solar fleet lists which makes it even more unlikely to be used
. I'd plow forward, providing support and swing the broadsides to bear around mid range. Is the Emperor better? yup you don't have to close to mid range to provide gunnery and you get twice as much launch for 30 pts
. With the Emperor your purpose is better defined also, its a dedicated carrier with just enough weapons to be a threat at range your going to reload without question if you need to and if your already loaded you might lock on, the Oberon is a gunship that someone thought would look good with some launch added I would want to lock this on every turn.
BFG-R rules are even worse Id rather have the 30pts back because its still a gunship first I want those guns working so I'm going to be closing anyway.
