Why most people dont like to tank?

[Kienkarajo]

There you have it: people are assholes that don't let newbs get a hold of tanking.

I guess I was lucky because I really messed up really bad when I was lvl 30 with my DRK to the point that I felt bad for the people that were with me and specially the healer since my main is a white mage, but they were really patient and they never rage quit, I think only a summoner told me that DRK's sucked but I actually made a mistake so I guess that was ok, I'm 52 atm and I feel that I can handle groups better. But I agree if all those parties had told me to quit because I sucked as a tank most likely I will be playing right now as a white mage again.
