I do not understand the purpose of this ability. It's 100 potency, with a DOT of 150 potency.

It makes no sense in any context. It doesn't do enough enmity to matter, it's half a flash in total.

All it does is damage, but that's not really gladiator's job at all. And even if it were, it's rather lackluster. Compare it to every damage ability in the game. Other DoTs are something you're trying to maintain at all times. Chaos Thrust, Phlebotomize, Fracture on Warrior, Touch of Death, Demolish, Everything summoner does...they're all supposed to be maintained indefinitely. Why is Circle of Scorn a DoT when you can't maintain it?

It doesn't make sense to even be an AOE. Paladin doesn't have any AOE abilities other than Flash. Dragoon has AOE cooldowns, but they also have doom spike and ring of thorns for them to support. Same with Monk. You can't really DO anything with the AOE damage as a Paladin.

So why does this ability even exist?
