Being able to "fill classes" is a relative term. Class sizes are arbitrary. Are they able to keep up with attrition is more relevant. In order to upgrade they have to be able to replace everyone that's leaving. Also, are people leaving? If people aren't leaving you maybe run into an issue with upgrade as well.
