Did they have shields in that game? Normally they don't Thrawns ones did.
Avenger and defenders had shields. Haven't played since 95/96.
TIE Advanced, TIE Defender, Assault Gunboat and Missile Boats had shields, the other TIEs usually didn't.
Your worst enemy when fighting a TIE Fighter were Y-Wings in head-on-assaults (because their laser cannons are close together) and anything with turrets that could shoot in the rear (particularly the Escort Shuttle, a single hit could damage you enough that you lost subsystems and might like flight controls so you fly helplessly into its next shots).
Your first enemy otherwise were A-Wings, because they had concussion missiles and it's hard to evade or intercept them unless you're flying directly into them, and again, a single hit can disable or kill you.
TIE Interceptors were more maneuverable, faster, and better armed, though they had one drawback: The wing-tip lasers were far apart, so you were more likely to miss some of your shots. The TIE Fighters central two lasers were perfect. And the way the game was setup, basically the more weapons you had, the slower their fire rate actually was, so two lasers meant you fired as much as with four lasers. The advantage of the 4 Lasers were more energy reserves, so you could keep shooting more often.
The Missile Boat was particularly ridiclous, it had only a single laser (plus up to 80 concussion missiles or 40 concussio missiles and 30 proton torpedoes or combinations liek that), and that fired rapidly fast. But you'd weapon banks dried out quickly.
