Just to clarify, the rules for FC Regional Crews allows for the INCOMING player to select a stage to play at. This allows the DEFENDING player to switch characters if they so choose.
This is a confusing rule so don't feel bad for misunderstanding it. All the captains knew the rule though which is all that really matters. The same rule will be in effect for FC6. People were chanting "Falcon! Falcon!" in vain because Isai's character was pre-picked. They were just overly hopeful.
I also have to say this - people need to shut up about Ken's sisters. I watched the video and all that happened was that they were sitting next to the camera, which was in the middle of the crowd. They were screaming no more than ANYONE else there. In fact, almost every EC member was louder. It's not their fault that they were picked up by the mic more than them. So do not insult them, they're both sweet and incredibly supportive of their family and it was an honor having them attend FC3.
Thanks.
