And what if no one provides feedback about the lore and the book gets released with those mistakes? It's a book. A book has more than just random letters that form words. A rulebook is more than "roll a d20". The game is the sum of its parts. If you don't provide feedback on all its parts, then you're not doing it right.
If you are playtesting a video game, are you only going to worry about "press left to shoot", or do you also look at the story, characters, art, and design? The answer should be "yes" if you know anything about playtesting and game design.
Again, you may have 30 years of experience with playing RPGs, but I am a trained game designer. Since they didn't say they only wanted feedback for the mechanics, I'm providing feedback based on the entire material they have released as part of the beta test. If they don't want to listen to that feedback, then it won't matter how "small" they started, they wouldn't be really good game designers to begin with.
But as I write this, I realize we're heading back into debate territory and as I said in my previous message that started this, I'm really tired of people arguing against me, no matter whether I'm right or wrong. So, once again, I'll be taking a break from here. We'll see if I ever come back, at least to this thread. But as this cycle is repeating itself more and more and peacetime is getting shorter and shorter, I'm growing real tired of not being able to share something without it turning into another argument over who's right and who knows better. The thing is, we're not talking past each other, because I wasn't talking to you. And we don't see things from different perspectives. You see it from your perspective, I see it from every perspective.
