Choosing a tank class..

It depends. WAR is definitely the most pug friendly tank, since you are capable of self-sufficiently maximizing your performance no matter how poorly the rest of your party plays. It is the least needy job in the game and so people that otherwise play very poorly (NINs that don't Shadewalker, ranged that don't Quell, a fellow WAR co tank that spams BB, or a SCH that doesn't hop out of cleric to shield for busters, for instance) will think you are just the bees knees.

DRK (and to a lesser extent PLD) on the other hand, really require team coordination to maximize, and if you try and play optimally on DRK in a pug group that isn't prepared to coordinate things like shields, tank swaps, and aggro management, bad things are going to happen and their dumb asses are going to blame you.

TL;DR WAR permits your group to play poorly as a team and ignore a lot of their utilities, whereas the other tanks force everyone to use their tools to the fullest if they want to get an optimal run.

Thing is....people read stuff like this, and think WAR's are gods, and no matter how FUBAR they play, we'll handle it no sweat. Reality says that fails miserably, because a lot of WAR meta is based on forum myths.
