What's the point of being on a discussion board if you're not allowed to discuss? What's the point of talking about improving the game if we should be censored into only saying the game is great the way it is. Ian and co. read through the stuff when they have time to get input and maybe see things from another perspective. If it's not flat out pointless hating, I don't see the harm.
I don't think anyone in this thread is calling them lazy and not recognizing the work they're putting in, they're just discussing things they'd enjoy seeing in the game.
