I only have one problem with this argument: X-wing is wargame-lite and has attracted many Star Wars fans who may not have played a mini game before in their life (like me, my girlfriend, my friends). These people may be feeling a little upset that the standalone expansion they bought is practically useless in their FLGS environment without multiple other purchases.
This is pretty much it. Most of you fail to consider the entire gaming base and continue to compare it to other hardcore, expensive hobbies when in fact, FFG created something that is far more mass-appealing and of course a bit more affordable of a hobby. That is why people like Rapscallion and myself, and hundreds of others, wish a few things were different, and can see where those things could be different, instead of blindly fanboy-ing over every new toy FFG makes and pointing at other hobbies to somehow justify the reasonableness of this one.
Nobody has demanded a refund from FFG as far as I can see, so stop dramatizing the complaints. Pretty much all that's been stated is that there's been a ton of new releases recently, and the trend does seem to be more money required along with more releases in order to keep up, and some of us more casual or competitive-lite players with less expendable income hope that it slows down a bit and the game's integrity does not become compromised through oversaturation or anything.
