The DF in itself is fine, but ever since MMOs started to allow cross-server dungeons, players have an added layer of anonymity, and thus, feel free to act as poorly as they want, with a fairly good chance of never running into said people again. Also without fear of having their "real" character tarnished on their server.

I know cross-servers have made wait times much better, but if they removed this part of DF, and it started to be comprised of people only on your server, I'm pretty sure a good amount of people will clean up their act.

I can't wait for the MIP system, hopefully this will help a bit.
