Is Tank the happiest/most satisfied role right now?

[Oizen]

1. The only tanks who feel relatively similar in rotation are DRK and WAR.
2. It's not easy DPS when the boss likes to throw something you have to mitigate into a double oGCD window.
3. DRK has no self sustain.

I don't think its unfair to say that tanks have homogenized to the point where all of them are similar.
