It's true, and it's unfortunate the discussion has been focused with 'historical realism' rather than what works best for the game. I find that players on the forums find it far easier to design civics by committee based on what pieces of history they are familiar with, nevermind these civics are meant to be played in an actual game, and are not part of a history thesis project. I have not seen a single player post the results of playing a game with their proposed changes, nor any comment on how the civic changes may affect how the AI plays and chooses civics. To me, that is the red-flag that indicates the discussion is not serious and just a method of showing off historical credentials. Worse, there are actual civics with real balance problems, like Mercantilism, and they get no discussion, because the civics that are more easily understood and debated suck up all the oxygen.
