My experience is that subs subdivide themselves at some size to become fractaly specialized. Like dnd 5 optimizers, dnd5 powergamers, dnd5 roleplayers, and when those get too big, dnd5 players that like to optimize wizards in the ravenloft setting while listening to lo-fi. There is an obligatory xkcd but I can't be bothered.
