Well, Ive only encountered a fllet with 7 X-wings, 7 Y-wings, 7 A-wings, 1 Assault Frigate, 6 Nebulon-B's, 4 Marauder's, Ackbar, and Luke, I destroyed their station and a bunch of their frigates and they retreated, But I use scouts to my advantage, I tend to see the enemy fleets before I attack and make sure I create one larger, oh they also had 5 Correllian Corvettes, and 5 Gunboats, and the Sundered Heart, but like I said I went for the station then took out as many of their frigates as I could before they ran.
