Crazy idea here:

How about you Devs load up the new client and let us play test it? This current client is horrible and broken (this coming from one of your biggest supporters). You aren't doing yourselves any good by continuing to show this current client to the few trickles of new players you get. I think wherever you are with the new client needs to be shown to the few people who are still paying attention. We've all seen the results of a poor Beta. I'd think you would want to correct that mistake at the root of the problem. Let us play test it! What's the worst that could happen? We're already playing on your dime.

I'd at least feel like you all are no longer blowing smoke up our arses with this new client.
