To recenter the discussion...
While Whitestars are shown to be Boresighted in the show, ACTA does very little to completely model the pure maneuverability and speed the Whitestars get, and the survivability that entails.
Firstly, they have, in the show, three weapon systems instead of the two given in ACTA, and possibly (I'm a bit too lazy to watch the seasons over to confirm) though unconfirmed, stealth.
Secondly, they are significantly faster than any other Capital ship in the game. ACTA does not model the vastly superior speed fighters and Whitestars have over "true" Capital ships. Whitestars flew circles around Omegas and Shadow Omegas. Literally. Even Thunderbolt Starfuries had difficulties keeping up. They were, in essence, Fighters with really big and scary weapons mounted on them, which is why they were so effective. They could kill capital ships, anti-fighter weapons couldn't really hurt them, and they were too fast for anti-capital ship weapons to hit them effectively.
Thirdly, Boresight was never an issue for the Whitestar because of the reason listed above. They were so maneuverable that Boresight was rarely, if ever a problem, and they easily strafed Capital ships. This is the primary reason the Whitestar has a Forward arc beam at the moment, to emulate or "metagame" the Whitestar's maneuverability.
Fourth, you almost never see a Whitestar decrewed in the course of a battle. It is, in the show, always crippled/destroyed before the crew is adversely effected (And the crew are usually adversely effected because of the gaping holes blasted in their ship). In ACTA, the reverse is true, where it is easier to decrew a Whitestar before you cripple it. ACTA does not emulate this for the Whitestar. Case in point, when Delenn's Whitestar is attacked, the ship is heavily damaged, crippled, which in turn decrewed it, not the other way around. The Whitestar would repair itself after the fact, but in the course of that short battle, it was crippled and rendered near inoperable before it was de-crewed.
In essence, to bring the Whitestar "more closely" to the show, you'd have to change it to something like...
White Star (Raid)
Speed: 20
Turns: SM
Damage: 4/1
Crew: 1 (Cannot be decrewed, like Technomage Pinnace)
Traits: AA, Dodge 2+, Flight Computer, SR1, AJE
Improved Neutron Laser: 18 inch boresight 2AD Beam, Triple Damage, Precise
Molecular Pulsar: 10 inch forward arc 4 AD Accurate, Double Damage, AP
Fusion Cannon/Pulsars/whatever: 12 inch forward arc 4AD Double Damage, SAP
