The biggest problem with Class halls beyond it mostly having Legion content in it is that it is far too heavily tied to Legion zones. There are only two class halls that are available from a location other than the Broken Isles. The Mage one could be given a pass since it is a fitting area that is easily available with the Mage teleport, but beyond that even class halls that were lucky enough to be in the actual overworld are all based on the Broken Isles, most of them are instanced areas only available from Broken Isles Dalaran.
So in short, if Class halls were designed to last forever then they failed at the first hurdle. Only 3 classes have it available in a way that doesnt require going to Dalaran, and only Druids actually got utility from it that was useful beyond Legion itself.
