While I understand your frustration about the lack of official new, your fixations about Saltypetra’s stream is kinda strange.
There is not once any infos are told exclusively in the steam and never available anywhere else. If there is an important information, someone will write a summary or create a new screenshot post, if the devs didn’t already do that in the first place.
For the new about GW, Saltypetra have already inform players about it, 3 weeks ago.
It’s fine if you miss that and want more clear answer, but assuming only players who watch the stream will know this is kinda wrong.
