That does not excuse behaving in such a way that only dis-incentivizes the devs from engaging the community.But that's the problem, they don't want any help. You could even say they autistically avoid valuable help and suggestions since the beta, at least we get very little feedback and when we do it's vague. If they are not reading the forums, what difference does it make what people post?
The few times few devs actually get involved in suggestion threads they are treated with respect by the worst ranters (except MP playes, those guys are feral trolls).
If you are not OK with the devs ignoring you, do not give them even more good reasons to continue to ignore you.
If I was a dev, and had good reasons to expect that a visit to the forum would only end up with shoveling through vent and rant threads such as this one, I would probably pass on that privilege as well.
