Thought i would add my experience with this and check if others had similar.
While I haven’t had any issue with any trivial non-boss mob, the Pile of Supplies/Eye Warden’s(?)/etc who are flagged as non-boss and have extremely high health pools are impossible to get down - I simply cannot burst or sustain enough DPS with an ice-shard build to out-pace the regen.
This started around L75 (T35 sigil) and now that I’m L80, sigil’s with this affix become instant junk. Even on dungeons without this affix, after clearing the accompanying mobs, you spend a loooong time finishing these off.
Not sure what the issue/fix is, you pick;
- Health pool too high
- % regen too high
- DPS too low (durr)
- Dont flag these as non-mob
- Bug
