dont get me wrong im not saying my psn necro CANT kill heralds- its just that they dont kill them particularly efficiently. Single target dps is not the strength of the build. You can absolutly down them it just might cost you a minute or two. And again, the density clearing is so efficient that if youre trying to clear an act, hes still a great choice IMO.
Quit lying to yourself lol. Emilio can't solo a T5 herald in anything but maybe 1p. The poison does hardly anything to them
