Shaulanca as 'Corsairs' reminds me of TAZ as 'Zoners' with, of course, significant difference, but bascially the same idea to fit a religious group with its own principles to the NPC faction that encourages similiar roleplay. The problem always comes when the 'cult' wants to roleplay outside the bounds set by the NPC faction.
From what I saw, Shaulanca's Corsairs-related roleplay is all about the Osiris in question - the snubcraft and gunboats can be picked up from various factions and be factionised or civilian technology. Uh, since we have the ID/technology system that allows weird deviations of roleplay to occure, such cases as Shaulanca that contributes enough to server rolepalay to be noticed, should be reviewed separately.
And again, roleplay is more important that limitation of technology chart when it comes to faction that requires a single Osiris that don't leave Omegas. Uh, I suggest Pirate ID, it's fitting the best way.
Zelot, you should actually know that Corsairs are meant to be more than some Corsair ships and Corsair enemies. From this point this black and white appproach tends to be really short-sighted.
