having a public server with everyone flying isd's wouldn't be fun at all, imo
90% of all level 30+ characters are using either the Eagle, Sabre, or Titan, so switching those into an ISD wouldn't be much of a difference for the current ship preference.
it would take a lot away from the mod if the makers didn't attempt to make it accurate
It would be accurate, a scaled version, but still accurate. You can't really get something accurate, unscaled, when the current weapon limit is far below the standard loadout of an ISD, though you could probably get the dimensions right as long as you have a good PC, or someone who can work wonders while constrained to a certain number of polygons.
i for one wouldn't be too keen on seeing an isd that was the size of a fighter,
I said it would be balanced according to the FL universe, which would imply that none of the ISDs or other capital ships would be the size of a fighter.
kewl part of a SWmod would be that it resembeled the SWuniverse instead of cutting corners whereever needed
Your use of the word "resembled" is a little loose, at least by what I think you meant. Even an ISD with cut corners would still resemble an actual ISD.
People complain too much. Guess you all can just wait for the space expansion to Star Wars: Galaxies, but of course you'll have to wait for the actual game first.
