The problem isn't necesarily enmity as it is now, but rather the fact that we don't need PLD or general tanks to kill things.

Voidwatch gave us a glimpse into how fights would be if every other MNK couldn't tank the hardest boss the game currently has to offer, and I assume it will continue to be that way.

Simply put: If there was an opponent that REQUIRED a job with the survivability of a PLD to tank, the playerbase would find a way to defeat it.

(Although with perfect defense and so many Ukonvasara WARs around there's no way in hell we'll be needing true tanks anytime soon)

P.S.@Swords: You probably get this a lot, but Bog Body and Moogles take extremely high damage (Over *2.0).
