There is a very real-world concern that if you stop mentioning an issue it falls to the wayside. This actually happens in business where you can report a bug in good faith, but because you thought reporting it once was good enough... you find a year later it was never resolved. Other issues that departments never stopped emailing about got moved up.
That same can happen here without communication on what is on the roadmap for Baldur's Gate 3. If we do not know what Larian is looking to improve/change, we're incentivized to keep writing about it.
Always enjoy Sharp's comments even when I disagree
And DragonSnooz's comment is insightful. On forums and other forms of social media issues die if people don't keep the conversation alive. I really think the chaining issue would be ignored if Tuco was hammering on it time and time again (despite a near consensus that the system is bad). On any forum I've been on there are usually about 10 to 20 high frequency posters.
People repeat their opinion because it's effective. We know this from social sentiment analysis -- there are tools that you can use to gauge the popularity of some political candidate, some brand or some stock.
This is why troll farms exist. Not to have that discussion but I been in communities that have been targeted by troll farms -- lots of new accounts saying the same thing again and again. Because saying the same thing again changes opinion and people who want to change opinions know that posts on forums count. I've seen people pump and dump a stock or kill a political campaign by hiring reddit manipulators (and I'm not talking about the candidates you think I am, the famous examples had their own manipulators working for them).
So Larian's CEO is asking fans to talk about "creative" ways they have yeeted bosses into pits. People who want to see the game changed don't have the power that the CEO does so they repeat themselves often and hope this influences opinion.
And Larian is kinda caught. It might have it's preference for what issues are discussed -- wouldn't you rather post photos of badgers sitting in chairs instead of hammering away on movement mechanics -- but they don't answer the questions because they want to keep people talking.
Why so little discussion on Solasta forums? Because the answer is probably in the patch notes . . .
