So in the eyes of the all-mighty cryptic ship balance dev (hi Geko?), 1100 hull points is worth +3 turn, +5 inertia, cloak, ability to use dual cannons and universal ensign. Balance like hell. That's either pure incompetence, or unprofessional bias towards Galaxy class.
And im not even talking about the more favourable console setup for Negh'Var and more offensive power bonuses.
