Game Mechanics: Necromancer Spell Threat

[Striiker]

I am running into this issue as well. I know that my pet should be doing a better job of holding aggro. There wasn't this issue until a couple of months ago when the aggro for spells was adjusted some how and suddenly, I could no longer sit through any fights while my pet was attacking. Prior to that, it was as it should have been where I could let my pet get aggro and then cast a couple of DOTs and not get aggro or if I did, it was brief until my pet taunted and did more damage.
I'm running into this a lot too with my enchanter where I get aggro way too easy now. I will try to document what I am experiencing better than this but I wanted to post quickly in agreement with the OP
