What are your thoughts on the complaining?

I see what you're saying, but a forum is a place for speculation and discussion on both sides. I don't think it's an issue as long as no one derails threads or is personally attacking gurus or otherwise out of line. Don't be positive in a negative thread or negative in a positive one. You (not you specifically but as a general term) don't have to go to threads you disagree with if it puts you out.

Personally I like the dedicated complaint threads because I know I can go there and voice my opinion, which often includes criticism, without people telling me to shut up and enjoy what we have. But I have also seen the reverse happen where people who enjoy the game are told "no you shouldn't be happy with it"

Basically do what you want in the appropriate threads, that's why we have them. Any need to police it further will end up silencing either the criticizers/happy players and we'll only ever hear one opinion.
