I have a few things to note.
1) For the majority of you who are complaining, which you are most entitled to, I suggest you email them, as just complaining isn't going to do much of anything.
2) For those of you who keep saying that the random characters rule is to keep everyone on fair game, that is totally false. All it takes is for a few of the players there to "randomly" be paired with their mains, and the rest of the poor suckers there using characters they are mostly unfamiliar with will be slaughtered. If I'm a Marth main and happen to use him while you get stuck with Mario, having never played him before, I will likely win. That's not fair play.
3) For those people who keep saying that they can't allow GC controllers to be used within the tournament due to modified personal equipment, macros and turbos, that is true, but not excusable. If they are supplying everyone their with wiimotes, which seem more expensive than the GC controllers, they have no reason to not supply the latter as well.
