I’m also running a Necro right now that’s around level 75, but in Season 1 not the eternal realm. At first, I wasn’t enjoying it as much as my preseason Rogue because it felt much slower. But recently my build (Infinimist following the guide on maxroll.gg) really clicked with the right gear and affixes and now I am absolutely FLYING through NM dungeons.
My buddy complained yesterday because his Pulverize Druid couldn’t keep up if we were in the same “lane” when clearing a dungeon.
With that being said, I can’t imagine playing the build outside of Season 1. The Malignant Hearts that autocast Corpse skills and Decrepify just make the build sooo easy to play. They autocast 3 out of your 6 skills.
