My only complaint, after playing tanks in various other games, is that I feel far too squishy in dungeons. Where, if the healer misses a heal or two, I'm dead. That's not something I'm familiar with, as most of the time tank classes have high defense and high hp, giving them survivability far superior to other classes. Other than that, I don't have many complaints aside from other players not able to tell how much enmity they have generated in comparison to the other party members.
