PLD any better than WAR?

IDK where you're getting your calculations, but a 20% increase in your defense is not 5~6% reduction in damage. In fact the real reduction changes with gear, so already, you've popped a hole in your own statement. The more defense you have base, the higher the amount increased is.

You know that the defense stat scales like poop, right?

Defense on armor barely increases with ilvl too.
The difference between an ilvl 55 tank chest and an ilvl130 tank chest is 21 def.

Foresight as it is now, and in the foreseeable future, is a pretty trash skill that you pop when you have nothing better to pop.
