DRK and GNB has a different playstyle than PLD and WAR... they all can do absolutely amazing feats, but it do require you dig into them all.

I can't use some kind of info from someone who only wants to level it to 100 for never again to touch untill next expansion.

Long term players and having it as prefered tank job, another story, but those people also got months if not years of experience with the job as it is and know each and one if them is extremely effective if played correct.
