I am very much disappointed by lack of official communication by Larian on game mechanics. Are they going to release a User Manual or are we going to depend on unofficial wikis run by volunteers/third parties for high level class/subclass features?

I am sure they have everything documented internally (you can't have a project this size without documentation, even mods done by volunteers have extensive documentation), so I don't get the reasoning behind not publishing. All we have some interviews and Tiktok videos.
