They neither must nor must'nt. It is all just wants and opinions.
But the fact is...
Look at who is djng on the east coast for Usadance and the collegiate network. What did he have before the split, before an NDCA dj left UsaDance and Collegiate and handed over the work to him? What did he have prior to 2015? What did he have in 2015 and now into 2016?
Look at who was judging and Usadance Nationals this year? What kind of judging work did most of those people have BEFORE the split.
Nothing. Yet they all have jobs now! Most of the judges choose UsaDance because they because they couldn't find work with the NDCA, it is so bottlenecked. And certainly almost all of them were not judging/djing a competition of prestige like a Nationals! The officials are better off now than they were before. Ask them yourself if they want to go back to the way it was before when the judges had 0 and the dj had 2 gigs a year to work.
My goodness there is enough work for everyone. Really. Why must all of it funnel through the NDCA first? NDCA letting go of UsaDance was one of the best things for UsaD and the officials who choose that org. They get all that work without having to stand in line for YEARS behind senior officials who aren't going away anytime soon.
How long do you think UsaD wanted to be beholden and under NDCA's thumb anyway since they were already making plans to start certifying/creating and using their own judges before the split. NDCA just surprised them and called them out on it publicly before they were ready.
