I flat out refuse to weaken it's health. The Venator had hull and shielding equal to the VSD-I, and that ship was by no means a glass cannon. Further, this would mean the capital Venators would not be able to go into battle and use their support abilities on the fleet, which would make them utterly useless. Additionally, the AI would not understand this and keep sending in Venators to their deaths. Also, the Venator's 8 main cannons were said to have equal or superior firepower to the ISD-I's 8 large cannons (4 on each side of the bridge), but not the ship itself. I'd say the Venator, which has a total of 160 DPS versus the VSD-I's 200, has more firepower than it truly had, and reducing that in favor of more fighters would be a very apt and canonly correct thing to do, though I could be wrong in this regard. Hadn't even thought about it's abilities, yeah, true.
