As someone who plays a tank, and always have. The reason why we don't DF with randoms is because of the mentioned answer below. Tanks get the most criticism in parties, always have and always will, healers come next in that line. As nasty as this sounds, suck it up and live with it, it's not going to change in a mmo. I am leveling my DPS job now and I also see the 30min queue wait times as well. I just do other things and live with it, if I dont get a spot i just cancel and fate grind, hunts or POD or go with some fc mates.
