From a game design perspective SE should make WAR tanking class focus on other stat than VIT, at least for the sake of making it different from PLD. We're supposed to have plenty of Vit to start with and our armors raise it even more so I'm thinking points should be spent on areas we are lacking.

I understand it's not the case so yeah I'm hoping SE will fix this. But on paper, I would want WAR to be designed to focus on STR/DEX for more parry and self-healing.
PLD have innate mitigation but need to buff their HP pool, WAR have the innate HP pool and should be designed to compensate their mitigation though parry/self-heal.
Hopefully, we'll get there eventually... I'm stacking on STR/Dex/crit accessories for when that time comes ...

I love WAR, love the feeling when I take a big hit and restore it back through my own means, really didn't like tanking as a GLD (to get my WAR prerequisite) and want to be able to enjoy tanking this way.
