As someone who primarily uses the forum I can totally see where you are coming from.
But wouldn’t what you describe maybe even advocate for an upgrade of the forum? The question is, why do so many people do not use the forum? Maybe with enough effort and improvement this could be changed.
Also EHG always uses the forums for large scale news and dev blogs, because some of these things are hard to display on 3rd party platforms.
You will never get any majority onto any platform a game uses. But if there should be a main or a biggest platform for a game, why shouldn’t the devs try to make that the official forum?
I am cautiously optimistic, taht the forum upgrade migh give it a overhaul that makes it more appealing.
