Splitting the tourneys up doesn't mean they will be held in a small gym. 321A is on its own and held in an arena and is a very prestigious event. As someone who wrestled and coached at a 2A school for awhile, I would say the event for 321A seems more prestigious than the event for 456A because everyone in the entire arena is focused on one thing. Fans can easily keep a bracket and the team scores are always posted and everyone is there for ONE thing and focused on that one thing. The workers can accodimate coaches, wrestlers, and fans appropriately, because it is not a big cluster. I bet you couldn't force a 321A fan, parent, coach, or wrestler to put up with the mess we 4A fans, coaches, parents, and wreslters put up with at Wichita.
You just can't imagine how awesome the finals are when everyone in the entire arena is watching the same match. It is electric! And people even watch the awards presentations and know the team scores that are constatnly updated. It is not just another tourney and you can tell.
