That's an argument I don't buy [that the game is boring because anyone is being "forced" into living in tank stance.] If your goal is to have fun stance-dancing, and squeezing out every inch of damage from each tank job, that ability is still there. You still can do a lot more damage if you opt to do that. You wont break game balance and do more damage than a DPS doing so, but that is claimed to not be the point.

I have issues with 4.0, but it's not that I cant do enough damage (I can solo stuff well enough, and as you said, I am viable at tanking.) My only concern in 4.0 is intra-balance among tanks. War may be viable, but relative to PLD and DRK, it is way behind.
