To respond to the thread's title question, I fall firmly into both yes and no.
No I'm not tired of complaint threads because there are cards and ships in this game that need to be looked at seriously. Adjustments need to be made. Some folks are not having a good time. Where else do they get to voice their displeasure? That's what message boards are for. Let's be honest, if this place was full of sunshine, peaches, and roses, it'd get boring real quick. How many "this game rocks" or "x-wing is great" threads would go around before certain people got tired of seeing them? Complaint in and of itself isn't bad, it can lead to real constructive debate, and that's a good thing.
Yes, I'm tired of threads complaining about specific cards because there a few fundamental flaws with the game itself. Fix those, and you may not need card fixes.
