I agree completely with the OP that there is too much negativity and 'rush rush' in the DF, and personally, myself and many in my group of friends, have taken to not even using it at all unless we must (low level roulette). This is sad, really, because then we may be missing out on meeting some nice people. Also, the fact that people like me (who are leveling WHM and PLD to 60) who choose, due to the potentially rude and intolerant behavior of some in the DF, to not use it, makes it seem like there is a shortage of tanks and healers. I think that the "shortage of tanks" and, to a lesser degree, healers, is really a "shortage of tanks and healers willing to put up with DF. The DF and some of the ways people behave like children when using it drives many of us away from it altogether -- sad, really.
