Might I say that this was one of the dumbest fricken missions of the whole lot. "Hey alpha, protect the Oberon from those stealth fighters. Hey btw, the Stealth fighters are invulnerable and you can't win."
YEAH, that's an excellent review of the stealth fighter's capabilities. Make the Pegasii invulnerable, and cut Alpha down to the player's ship only and anyone could smoke all of those dumb stealth fighters.
A better way to have done it is to have the Pegasii vulnerable (maybe guardian) to damage but becoming invulernable once they go below such and such a level, and when they go below that level they break away and abort the mission. Get all the fighters to abort and you beat 'em.
At least the TAG mission was semi-amusing. But even so, whose going to use TAGs? The player wants lots of kills and giving those kills to some allied warships is not the way to do it.
