I literally said everyone, and never mentioned GMs. You've fabricated a strawman. GMs are part of everyone.
IF you are are GM where that class was playtested, you have just engaged in a playtest of that class. It's a neutral question. It's not tailored to the player. Nobody is more equal than another. GMs are not being oppressed or dismissed by the playtest. In fact, the instructions under "How to Playtest This UA" talk about DMs and creating your own adventure for the purpose of playtesting.
I am absolutely not dismissing or discrediting criticism. I have my own criticism. But when you make a public post here on a message board intended for a back and for conversation, you don't get to complain about getting feedback on what you're saying.
Yes, that was me. That, because someone might like both the old and new rule exactly equally and exactly as favorably, it is no harm to those people's views to assume that maybe you need to pad to account for that. You were saying some votes should be dismissed which WOULD harm the views of those voters and I explained how that's a different situation - dismissing voices who care about their view being heard is not the same as dismissing those who suffer no harm from it and are fine with it.
That's you putting your ethical view on other people inappropriately. No, you as a DM do not have a more important voice that others who consume this product. But EVEN IF YOU DID (which you do not) it would still be wrong to split it not between "DM vs Player" but instead between "DM vs a specific type of player you personally don't like." There is absolutely nothing objectively good or righteous or just about your view. It's you saying your view is objectively better than the views of others for no reason other than it's you.
No, it's deeply irresponsible to assume a type of player's views is a "distortion" because you disagree with it. You're essentially saying, "I don't like the color blue so anyone who likes the color blue should be "corrected" as a distortion because I don't like the color blue and therefore blue is a distortion." It's circular logic and has no basis in any kind of ethical view.
