You can't really avoid some players in every game with that kind of an attitude. I've honestly felt like it has been a little better recently. Random DF people even put up with my attempts at learning to speedrun dungeons on warrior a few weeks ago. Last time I tried that was when Brayflox HM was still new, and the rude comments people made back then led to me quitting tank until just recently.

Anyway, I agree. "Don't be a dick" is something I live by when interacting with people online. I think we all want this game to succeed as we move forward into Heavensward and beyond, so treating everyone (especially new players) with respect will go a long way toward that.
