Dont drop anything then, lets fix stuff.
Victory: The only problem I see with this is that it makes the Apoc obsolete, luckly now its only available to Bakka and should remain as such. Change the dorsal to 9wb@60cm, with those stats I think it should fall in at 355, 345 with Torps.
Vanquisher: Is this an Emperor or Retribution hull, it looks like a mix, anyway... This is an oddball, it looks like an Emperor with lances instead of launch, I think Id drop the weapons range to match the lances and boost the torps up to 9. Leave the dorsal empty and price it at 325, give it the BFG-R option to swap its torps and 6+ prow for 4 launch bays.
Leave the Jovian as is, move the Dominion to the Bastion/ Solar fleet lists.
This leaves our carrier options as:
*Freely available
Vanquisher (battleship requirements, BFG-R upgrade)
Emperor (Rath, battleship requirements)
Admech Dictator (battlecruiser requirements)
Admech Defiant (battlecruiser requirements)
*Reserves
Emperor (battleship requirements)
Exorcist (grandcruiser requirements)
Jovian (battlecruiser requirements)
Mars (battlecruiser requirements)
Dominion (battlecruiser requirements)
Dictator
Defiant
Im sure Im missing some here but this seems like plenty of options for carriers.
Mercury: 255pts
Cruiser/8 Speed/25 Turns/45* Shields/2 Armor/6+|5+ Turrets 2
Weapons: 6@45cm 4@60cm port and starboard
Lances: 2@60cm dorsal L/F/R
Nova: 1 Prow
Special explosion any ideas? I think it should just roll 6 for a plasma instead of 4 and 12 for a warp instead of 8 since it has battleship powerplants instead of rolling 3d6 for catastrophic.
Rath:
Leadership 10
2 rerolls
+1 when defending against boarding
ship refit
weapons refit
This certainly doesnt seem like its worth the same as Abbadon but anything less than 150 seems a bit low.
