I only play with friends anyway, but all the DF PUG issues people complain about are normal for an anonymous/cross-server instance game. The OP is right, though they'd never get rid of cross-server. The sadder alternate downside to cross-server content, IMO, is when you have a GREAT party of good players who are also good people... and then you have to go back to your server. I wish the game used megaserver tech.
