I am distrustful of those that come here and claim fathan is gimped as I suspect those same people are probably playing fat-han builds themselves and doing what they can to keep their build from getting hit with the nerf bat.
Except the design team spends exactly 0 time perusing these forums, so nothing said here will have any impact on any decision they might make with the Falcon.
I play a four squint list in almost every game so take what i say as you will. I can kill a falcon if I roll above average and my opponent rolls below average. odds will always be in his favor though.
So either accept that you start with a disadvantage or fly another list. Good and bad matchups are a part of every competitive game (by competitive, I mean a game where the object is to win, not necessarily WAAC style play) out there. You accept that any given list will give you a better time in some cases, but will struggle in others.
My first point stands though. people will always try to justify their behavior.
Second point is No, I will play my four squints because that is what is fun. It is not unrealistic for me to expect my four ships to be balanced verses other ships and if I should feel forced to buy new ships in the name of competition than that shows bad game design and possible a bit of manipulation on FFGs part.
100 pts should always be competitive against 100 pts.
