I research what exactly people are disappointed with. If I see ten posts complain about AI, those ten are often talking about very different things, not all of them are even AI. So I have to sort out what the actual issue is and then let Johan and the others know what the consensus is.
Personally, I feel for the disappointed ones and want to help make the game better. Sometimes people will get nasty and then I'll ban them for the benefit of the whole forum, but generally, I think people can express themselves well. Complaints are ok, constructive complaints I welcome.
