A Mastery stat would probably increase Tenacity for tanks and Piety for healers. I prefer the system we have that just makes a category for Role, otherwise the stat names become lackluster and we may as well just get rid of substats and have pure potency, weapon damage and attack power.

I'm not entirely sure why spell/skill speed increase damage instead of rate???
Because there is a fixed tick rate of 3 seconds and increasing the damage has mostly the same effect as increasing the tick rate, which is increasing overall damage. Probably a workaround.

Versatility is basically determination, but better (increases your damage and healing by a % and reduces damage taken by half that percent).
So it's Tenacity.
