Game Mechanics: DOT behavior

[Potus]

I don't think so. You should be completely wiped from aggro and that DoT doesn't belong to you anymore.

I'm basing this off of the fact that I used to pull Sir Lucan to the zoneline, Dooming Darkness him, and then zone. Come back in and he's standing still from the snare, and his HP is out-regening my DoT. The rest of the guards are walking back to their posts and he would not aggro me.
