Couldnt agree more with Graf Spee, that ship is orders of magnitude more powerful than anything else in the game, it just doesnt work on any level im affraid. If you really want to design a ship i would really recommend dropping the quadrants idea, and increasing the hit points. Also, 6+ with 6 shields is just silly imo, but hey its your ship!
Real Men/Women/Aliens/Heretics/Warp Spawned Filth/Big Scary Space Monsters play Battlefleet Gothic... why dont you???
