Communications/PR seems to be just about the only function that Larian isn't looking for on the main site "Careers" page. I'm wondering if PR strategy isn't outsourced, and Larian takes their cues from that outsourced company. Which mean they (PR company) might opt for an option that will be cheap for both them and their client (thus not spending lots of work hours here on these forums), but instead focus on rarer, but (in their hopes) also more informative major dumps of new information. So, instead of feeding us little snacks more regularly, we'll get more impressed when we suddenly see a major feast decked out for us after a long time of growling stomachs.
The one-way style of PR, is something I've seen while working at a fairly large, multi-site/exhibits (historical) museum. There were multiple curators and archaeologists at the museum, spread across the whole of our designated region, and those curators all had exhibits they wanted to communicate to the media or the public about... but that HAD to go through the PR manager, who unlike the curators and archaeologists, was part of top management. And frequently the curators and archaeologists desires to get something advertised in the papers, or a find shown.... was simply shut down. The PR manager wanted full centralised control and thought that it was good enough that we simply advertised these news on FB and via newsletters to the people who had signed up for those. Mainly because that was cheaper. Her biggest contribution was an automated Google review reply to comments that went: "Thank you for leaving a review. We regret we cannot answer it, but we appreciate you taking the time to read it. Be assured we read all reviews." Nothing says appreciation like robotic messaging...
Anyway, point is PR may have persuauded upper management that they're really, really professional - which sadly doesn't always mean that they're good at what they do. And then upper management will let them carry on doing their thing, and will go along with it because they looked at their resumes, which looked fine.
A focus on mainly one-way communication might also simply mean that management is worried that (non-PR) employees might inadvertently divulge spoilers, new races/classes, or other features or news Larian wants kept secret so far. This ought to be possible to manage, but I am not sure about the culture of Larian studios. Some work cultures are, as a result of the country's culture that the company is based/originated in, very top-down hierachical (French, Anglophone countries), some are almost the excat opposite (Scandinavian).
I think I'm leaning towards worrying that regular Larian employees might divulge information Larian wants kept secret. Not neccesarily because they "distrust" their employees, but because they believe it "sends a message" of the company not being seen/thought of as really in charge, if PR isn't handled in a top-down one-way manner.
