defense doesn't help all that much - but increase size is cool
Defense is nice when your tanking large groups of mobs and not so much when tanking single target hard hitters.
Defense is more effective when getting hit by a lot of smaller dmg then it is being hit by one big slow attack. And since most of the tanks are tanking raids and challanges its still pretty helpful. But then again really the only decent boss tanks in the game atm are Spidey and BP with 80%+ dodge.
