What if Tanks were designed like Healers?

So you're saying the 4.0 Warrior ability, Uprising... was stolen from the joke job that wasn't released until 4.5?

Spirits within and upheaval. (Stormblood)
Spirits within: Delivers an attack with a potency of 300. Potency decreases as HP decreases.
Upheaval: Delivers an attack with a potency of 300 Potency decreases as own HP decreases. Potency also affected by maximum HP-increasing effects granted to self.

The latter is a better designed version of the same concept because it interacts with other parts of your kit and you have more flexibility with it.

Calling anything a joke job when your main is listed as machinist is asking for trouble.
