This spell doesn't actually seem to do what is claimed, if anything at all. I can chain-cast it on a boss mob with pet on it, and I -still- get agro over the tank. If it's really reducing 500 agro per pop, I should be the very last on the threat list. Yet, I'm consistently the highest.
I'm not even sure it works for just regular spells for that matter. Has anyone actually PROVEN this spell to do anything?
