I only level tanks. Once I a done with MSQ on WAR and I have farmed that job up to keep pace wit the next story patch and upcoming content, I'll be right back in the DF queue with my PLD and DRK. I always queue random after I check with FC to see if anyone needs a tank for speedy queues.

I like tanking in dungeons, and I am long past the point where one or two bad teammates in a DF will bother me even a little. If I get "helper" DPS doing pulls, stealing enmity, etc...I don't much sweat it, especially since SB decided to stealth nerf tanking under the guise of shifting the HW speed run paradigm to something more traditional.

But I'll be in the queue. No worries.
