Just like to chime in on the, "Go level a tank!" responses. My first job to 50 was Paladin, I then chose to level Monk. Sitting in DF for 20-30 minutes at a time, even longer before the DF changes, isn't going to be alleviated by switching to my tank. How is that going to level my Monk?

The main problem for me with playing a tank in this game is it is rarely fun and more often than not frustrating and punishing. I played a Paladin and Ninja tank in FF11 for over 6 years, a Paladin in Everquest for 4 years prior to that, and generally gravitate towards tanks in other MMOs. I enjoy tanking, I enjoy being that guy between everyone else and the mob saying, "You shall not pass!" Tanking in this game is simply not enjoyable for me, that might change if they add a new tanking job but the crux of the matter is encounter design is 99% dodging the big circle/cone of death and the unfixed and ever present lag in this game makes that problematic at the best of times.

I can handle a healer sucking and not healing me in time, I can handle derp DD who attack random mobs or try to pull hate off me for shits and giggles, I can't handle dodging crap on my screen and yet still being hit. Until they either resolve the glaring lag issues with this game or find a different mechanic other than AoE dodging to test players I don't ever see the tanking contingent being bloated in FFXIV.
