Judging from experience, I would say healers are slightly more in demand than tanks. I've been in more situations where we were missing 1 priest, than in situations where we were missing a tank.
I have been leaning towards a monk tank. If you had fresh start on Kr/Sea server along with everyone else, do you recall anything resembles discrimination towards a certain tanking class in dungeons? In some new games/expansions, players tend to accept nothing but the stereotypical class+role combination for awhile (i.e: Only knights tank, only priests heal, etc), until all classes which can also fullfill those roles were widely recognized. Was this the case to your experience? (I am aware of the different areas of expertise each of the four tanks are competent in)
Thanks for answering these questions.
