I think we've got a wire or two crossed. I'm not a battered fan of Shadowrun, I'm a writer for them. When I'm telling you that a lack of proofreaders isn't the problem, please believe me when I say that. I've seen the number of proofreaders we have. I've been a proofreader on some products in the past. I've seen and produced proofing notes, editing notes, and playtesting notes aplenty, for SR5 and other products. Proofreading is happening, and quite a lot of it. I can't go into details, partially because basic professionalism doesn't let me, and partially because backstage discussions are under NDA, but the suggestions you're making? They're not new suggestions. The concerns you have? They're not new concerns. It isn't that my "style" isn't to speak strongly and clearly -- speaking strongly and clearly is, in fact, how I make my living in not one, but two, jobs right now -- it's that there are limits to how strong and clear I can be (for legal reasons), and there are limits as to how strong and clear I want to be (because it's all things I've said before, over and over again).
That said? I'm not trying to silence you. I'm not trying to throw my imaginary weight around, I'm not trying to bully you, I'm not trying to browbeat you. I'm trying to save you some energy and enthusiasm. I'm trying to explain to you that it's arguments the Powers That Be have heard before and that they have then, for various reasons that it's not my place to go into, they have acted on, or not acted on, these arguments in their own way.
Everyone is well aware that editing and quality control are ongoing issues (or you wouldn't see us freelancers scouring errata threads and compiling errata documents, on our own time and of our own volition, or posting our own personal errata documents on Google drives, or clarifying with our own errata forum posts when we can). I understand and appreciate your passion and concern, but please be aware that you're not saying anything we haven't all heard, and (again) often said, ourselves.
While I find your posting style abrasive, that's not why I'm responding to you. I'm just saying, the problem -- as clearly and politely as I can put it to you -- is not a lack of proofreaders. So suggesting more proofreaders, much less suggesting full public beta tests, is not going to solve the problem, and is also not a suggestion that hasn't been made in the past.
