The Rebellion was quite undergunned. The MC80s in EaW were WAY too powerful compared to the Imperial Star Destroyers. Keep in mind that until the New Republic, this was just like taking a gun, putting it onto a cruiser liner and calling it a war ship. The MC-85 is the best armed and defended ship you'll get as the Rebels, though it still takes more than one to take out an ISD, and they cost quite a bit...
it would ne nice if you did like eh, some mod i cant remember the name of, where the ships have no hardpoints, just hundreds of firing bones, it looks amazing!
I've done that before with a few ships. I didn't like it very much. Ships still have the same amount of firing bones, with or without each individual hardpoint being destructable.
