My .02 cents on the subject of the G'Quan.
Of all the ships in both the show and fleet lists, the G;Quan is closest to the Omega in both function and form. To be honest, with the sole excpetion of the Emine system, they should be near identical in terms of weapons, speed, manueverability. Both ships fire red main Beams, both fire salvo pulse fire, both are portrayed as being somewhat slow and unresponsive to the helm. Its the best comparison to use when judging something that is subjective, namely each ships "usefullness" and power levels. As such,
G'Quan
Speed 6
Turn 1/45
Hull 6
Troops 8
Craft: 2 Frazi
Damage 58/14
Crew 64/17
Traits: AF 1, Int 1, JE, Lumbering
Heavy Laser Cannon 30 B 6 Beam, DD
Emine 30 F 4 AP, TD, OS, Energy Mine
Medium Ion Cannon 10 F/A/P/S 8/12/12/6 TL
Changes
Damage 58: Justifiable in light of Fluff. G'Quans are supposed to be tough, and at 58 is the biggest damage track of the Big 4 battle PL ships
Crew 64: Much higher crew than any other battle PL even after being lowered, I've yet to see any Fluff that says G'Quans are that overcrewed
Interceptors 1: Arguable here, on screen evidence, but no fluff justification
Heavy Laser Cannon: Been argued ad nauseum, pushs it to Omega Levels
Emine: Loss of 2AD. Despite arguements to the contrary, I've never viewed Emines to be a "ship-killer"( I still think TD is OTT, DD with slightly more AD would have been better), but rather a "force degrader" used to soften up opposing ships before actually engaging with beams and cannons. Also need to Justify the 2AD beam increase.
Pulse cannons: Dropped. I've never seen torrents of Pulse fire pouring from G'Quans. Even at range 8, G'Quan secondaries are brutal ATM, packing far more than any Raid and Below ship(In fact, the G'quans and Bintaks are very odd in this respect, that all round huge AD is out of character compared to the rest of thier fleet).
Light Ion Cannons: Slightly reduced AD, and rearranged somewhat. AD added to the sides while reduced in front and Aft. Beams are the main up front armament, aft has some big honking engines in the way. Side AD increased to add to its capabilities in the brawl.
Summary: Of all the changes, only the Addition of Interceptors bothers me, and is the one that doens't really feel right. I feel the rest of the changes much more accurately reflect on-screen evidence of the G'Quan, and keeps much more in character with the rest of the Narn list(actually I'd suggest doing the pulse/ion cannon changes to Bin'Taks as well). Emine AD might be too low, and bumped back to 6AD might be necessary.
