IMO, one of the flaws of X-Wing is the low values they use for stats. I think the game would of been better if they had gone with stats like...
Rookie X-Wing PS2, Attack 6, Defense 4, Hull 6, Shield 4
Academy Pilot PS1, Attack 4, Defense 6, Hull 6
May of made the game take longer to play, but with more dice, the amount of factor luck would of had would be reduced greatly. Plus then you have more room for other ships.
A B-Wing for example could of been Attack 7, Defense 1, Hull 8, Shield 10.
You avoid some of the Attack Wing problems in that the defense dice also scale up, where that game just has red far outnumbering green. That would seem to offer some more granularity at first, so any one bad dice roll then does less to you, but I'd worry about that also increasing the gap in efficiency between attack and defense dice, since they have twice the number of blanks.
