Well, I am a creative one, that means I do not have thick skin. If I had thick skin, I would be stubborn, and claim that my idea are excellent regardless. But, I am not so stupid I believe that everything I post is wise. The thing is, when you are smart you realize that for the brilliant ideas to pop out, you gotta come with stupid ideas too... - and - when the stupid ideas are stomped on by mean people, well, then the brilliant ideas won't come out, because vulnerable people like me will simply stop posting. Also, some ideas even if they start out as pretty stupid, by helpful feedback from others can grow and morph into something that is really great. You never know.
I can use my creativity and skills on other things, in situations where I do not get destroyed just because I tried to add value.
And, rather than tell what could make the game better, in my opinion, I can just accept how the game is, without changes, and when I do not think it gives more than it takes anymore - I can simply stop playing it. There are lots of other stuff availiable that I can spend my time on. I simply do not want to spend my time on trying to put my head forth when I experience people try to chop it off.
Unless this issue gets addressed in the forums, I predict that the activity in the forums is going to stay fairly low.
If you then want to close off the beta for only those who are posting on the forums, well, fine, then I just stop playing on the beta.
why should I care? - it is just a game. Maybe I will even thank you for releasing me from something that was not good for me
