Also keep in mind these are the basic Ties and X-Wings. Remember that X-Wings are probably almost twice as expensive as Ties, meaning that if a plain skill 3 Tie is 13 pts, a single skill 3 X-wing is probably about 20-26 pts each. Advanced Ties and Y-Wings, etc, are going to be more expensive each.
I think that the difference in points between the X-wings and Ties won't necessarily be the pilots but the number of attachments like Astrodroids and weapon cards that can be equiped to the ship. At the bottom of each pilot card it shows what kind of upgrades that star ship can have.
I hope that I can field a good 3 ship Rebel squad to make it feel more like attack runs more than just a bunch of ships going in 10 different directions. Also I'd like to see/play a 6 player game (like the one from last years GC) where each player gets to pilot 1 or two ships and work together.
One big difference between X-wings and Tie fighters is Shields. X-wings have shields and Tie fighters don't. X-wings, with 2 shields, can take 2 more damaging hits (or points of hull damage?) more than Tie fighters can. That's pretty powerful, and that alone is worth an increase of at least half the cost. So a Tie fighter costing 13 would equate to an X-wing of equivalent skill costing at least 19-20. That is without including other features, such as attachments and weapon cards.
