@sylph_ Farms usually announces the balancetalk-streams in the announcement-channel on the FAF Discord and it should be on the news as well afaik. so that's definitely something to watch out for. Besides that I do remember explaining the vision change like two or three times, however I cannot tell you whether it was in public, in DMs, ingame or in the FAF-client since I'm active everywhere. There is also an explanation here though? Even tbf that wasn't the first thing which came into my mind but I was pretty biased since I've talked a lot about it in the past.

If you don't get an explanation in the stream, feel free to ask in the chat - that's the whole purpose of it.
What I did forget to mention in a previous post: There sadly are so many clowns/trolls already which ppl don't take serious anymore nor listen to, compared to actual useful posts they clearly dominate. So it's really easy to get put into that "troll"-drawer.
Not exactly sure what you mean with the "which voices are relevant to the game types"-part. Imho as long as the player is good at something, I try to understand their thought process more. E.g. it doesn't matter whether you play ladder, gap, astro or 4v4 TMM, if I read smth like "I just kill sniperbots with two bombers all the time" it's simply an opinion I don't value as high cuz it completely ignores the existence of shields and AA. There are patterns however, e.g. <1200 tend to waste a lot of mass, or gappers tend to snipe a lot and turtle, or ladderplayers tend to avoid mex upgrades etc., so it's not really a question I can answer in a simple reply like this.
I was actually thinking about something the other day though, it kinda fits your last paragraph. Since I've joined the balance team for the simple reason I play low rated games and get their opinion, I was thinking about being the "go to"-station when asking for a (serious!) balance-take. E.g. the TML-one which I'll mention in a meeting. But since I know that I'm not the most non-toxic person on FAF, it's not as easy to tell whether it'd help or how I should even announce that effectively; The core thought of "balance team are elitists and 2000+ ladderplayers are the only relevant people" is simply way too deep in some minds out there.
