Game Mechanics: Necromancer Spell Threat

[Ropethunder]

The necro snare line is a huge aggro getter. This is actually a GOOD thing for kiting at higher levels where mobs will eat your pet.

This issue is related more to summoned pets not generating the agro they should. Once you get higher in level and find zones with undead, use charmed pets and it acts like you would expect with the side benefit of better dps.
