Sacred Cows?

[Whisper]

Then, by all means, point a leading TT RPG in expansion whitout the "sacred cows". It's all fair to request the argument of doubt, but you need to present a viable alternative. If they were really "useless sacred cows that make no sense and need to be butchered at all costs", don't you think some gaming company would've already came out there and dominated the market with it?

Ah, the old "If it were a good idea, someone would have done it already" fallacy.

If that was an actual fallacy, someone would've already came up with a fancy name for it.

Or an idiom?
I'll raise you a "Best is the enemy of better."

Sounds like a variant of Appeal to Tradition to me.
