The only good thing about Hammer of Light is the animation really, it rarely crits, when it does it’s alright but when it doesn’t, which is most of the time, you’re literally hitting people and most of your damage randomly hits someone else.
I think it’s also bugged in PVE sometimes as well had a ret doing insane damage in a key with almost no gear. Not 100% sure, I know they do have good up front burst but it might be related to what is being observed here. Shrug.
