As a Paladin, Circle of Scorn feels a bit.. lame. I use it to help with damage and threat but honestly, it's not much plus the cooldown is ridiculous considering there's barely any benefit from it. Spirits Within has a silence effect and does tons of damage with a close cooldown. I wish they change Circle of Scorn and make it so we generate threat from mobs immensely with it. Then I would be more happy having it. The animation is nice at least.
