First: enemies killed by Smite sometimes do not “die” and keep getting smited until the skill expires, at that point their bodies ragdoll on the ground.
I’m not talking about the “throw” that happens whan you stop channeling before max peril, and it’s kind of random so I suspect it depends on which body part the attack was hitting.
Second: sometimes enemies just keep attacking/walking while being smited. It could be that a whole horde is stunned but a couple of them just attack. It’s very dangerous when it happens with Ragers or Crushers.
