The return to previous subclass levels shows how difficult it is to change the deep structure of a game, once it is put in use.
I don't think subclass levels are a 'deep structure' element. Especially given how haphazardly they were thrown about the first time.
It's just that their default stance is to just reprint 2014 as is, so anything that doesn't get only glowing praise? Back to 2014 with you (see: exhaustion).
