This I can get behind. Simpler way to implement enmity decay.
It should rule enmity, but in FFXI right now it might as well be the only factor. Damage is the largest source of CE when really it should be mostly shifted to VE so DDs can actually shed hate by turning around.
In any other game NIN tanking would have gotten nerfed to the ground and effectively purged. It was along the lines of Reckoning Bomb and Evasion tanking, both of which warranted their respective nerfs.
Trying to arbitrarily assign roles to classes is the wrong way about it, because then you get surprised by things like NIN tanking.
It'd be easier to build a roster of tanks if you further develop the tools and assign the role to jobs it would make sense to have as tank. Not to mention "roles" get forced down your throat regardless of whether the game is assining them or the players are. So not much changes in that regard.
