What gives us the impression of a "brush off" are comments like this:
This is really a "soft launch" to evaluate how well the system performs with a large number of users. I mainly just want everyone to play the game so I can see what kind of server resources I might need to allocate when I start launching more leagues. Unless there are some glaring issues that are exposed over the next month and a half, my plan is to do a full public launch near the end of July.
If you do experience any issues, please post in the "help" form.
Feel free to discuss feature requests as well, I don't plan to expand the feature set before the launch but do have a large array of plans. The "beta" tag will probably remain for a while until I get through most of the features I want to install and the game has been running stable for a while.
I know Jon has talked to some people, including myself, about additional feedback privately. However, the only thing I have seen in writing are things like the above which says "eh, its fine, no need to change anything" (unless its a game engine issue).
Please take the criticism/concern as us caring. We want this to be a quality, successful game. If we didn't care, we would just walk away and not say anything.
