As a larger part of the issues at hand, much of the problem lies in the fact that we simply hold low expectations of the DF and the players we run into there. Be the change you want to see. Play well, and accept nothing less than others doing the same; no more "it's just DF so whatever". This is a measure every player needs to take in order to see improvements happen.

Just as it's generally accepted as good etiquette to not pull a hunt early, or join a farm party without having cleared content, don't join DF content without the willingness to adapt and cooperate with your party (within reason), and play at your absolute best.
