I tank mostly, though I also like to do DPS on my Lancer and plan to try Thaumaturge and Black Mage at some point. I find tanking to be somewhat stressful at times but mostly once I have learned the quirks of a dungeon to be fun and somewhat relaxing. I set the pace, I am responsible for much of the success based on my decisions, and I enjoy holding threat. I think why some people dislike tanking is simply that tanking does not really generate big numbers and there is a sense of responsibility that is very visible.
