The damage on a tank is generally abysmal, as everything that *would* be damage is actually 'fake damage' ("threat").
Damage is not a Tank class's priority beyond what is necessary to hold enemy attention and generally have a large enough HP pool to give the healer something to do.
-Trash is more strenuous for tanks than boss fights, as you have a lot of active damage going around and there's a greater risk of something being pulled off you if a DPS is being derpy.
-Bosses are typically tank & spanks with footwork. Very, very rarely do you get anything that requires brainpower like Coincounter dodges, ADS silences, and Garuda EX Phase Matrices.
Gear for Warriors and paladins alike reinforce the balance of strength/vit in general, in fact, 'pecking order' among tanks is usually done by HP.. while Strength and Determination may seem 'helpful' for soloing, it's maybe a .0001% improvement and a misguided notion that you can 'make up' for the lack of damage output.
