Home One, through film analysis has been calculated to be in the realm of 3200~3700 meters. Sourcebooks typically list it between 1300~1500 meters. The problem, as Jay as pointed out, is that pointing to any source is a matter of interpretation, and that really the specs we use in this game exist for gaming.
Clearly, we need the MC-90 to be an ISD equivalent. (Sorry, ISD-II is still gonna be the #1 gun). So let's compare stats:
ISD
Shields+Armor = 3200 / Damage Ouput = 1140
Units: 6 SF Squads, 36 AUX, 20 Support Units, 1000 Infantry, 60 GAVs
What the MC-90 needs to be for balancing:
Length: 1400 / Shields: 2800 + Armor: 1400 = 3200 [check]
Damage: 75 TBs + 30 IBs = 1050 [close enough]
Units: 8 SF Squads, 24 AUX, 12 Recon Y-Wings, 12 Medium Transports, 1200 Infantry, 60 GAVs [check] but for cost balancing and to lower the Command Points, let's realistically remove the ground units, because Mon Cals weren't assault ships anyhow.
Okay, so let's draw up the new specs...
MC90 Mon Calamari Battle Cruiser (MC90)
Cost: 2000 KCs
Production Time: 20 Days
Length: 1400 meters
Hyperdrive: x1
Shields: 2800
Armor: 1400
Hull: 1400
Systems: 700
Speed: Slow (1)
Maneuver: (2)
Weapons:
75 Turbolaser Batteries (900)
30 Ion Batteries (150)
10 Tractor Beam Projectors (1000m)
Onboard Units:
8 Starfighter Squadrons
24 Auxiliary Craft
12 Recon Y-Wings
100 Infantry Squads
Notes: Previously functioned as the mobile headquarters for all Rebel Alliance activities. Now being the standard bearer and ship-of-the-line for the New Republic, the MC90 Cruiser is capable of giving fleet commanders the power they need to command systems and ensure peace and prosperity for democracy. Includes a HOLONET transceiver. Can only be manufactured one-at-a-time at MON CALAMARI SHIPYARDS. New Republic or Rebel Alliance players can acquire this vessel at the Battle of Endor if they so choose. If taken at the Battle of Endor, the Rebel Alliance will get an MC80 for their Endor PDF instead.
This MC-90 gives you the same firepower as a Star Destroyer IN SPACE. Taking out the ground units was the only way to lower the inflated cost and CP value, so that's what had to get done. This is a really good ship, and at 20 CPs you have room for 1 more ship (or two) easily.
This MC-90 will be the *official tweak*.
Now.. any other last minute requests???
