I would venture to say the wording is inherently muddy, and that just might be on purpose. If everything were to be written down as far as how far you can stray from the rules, we might have realms doing what the fighters do.... min max. This way, if a realm goes too far (and by too far, I mean some analogous benchmark that should not be listed), we, the DGBA, can intercede. And typically, we don't do that unless our copyright is being infringed upon. It seems the second things get written down people immediately go straight to the bottom of the list and play there. Which is where we get this constant mantra, "so and so is unrealistic, why not just...." It happens all the time.
This way, if some realm goes way off course we can say, "Yo dude, too much". That is our way. No one here wants to play evil overloard or be da man or be da power, we are hippies and miscreants, we fight the power, and we stick out out middle finger at da man.
