Game Mechanics: Pet Targeting NPCs

[Grozmok]

I've been having an issue with skeleton pets on both my SK and my Necro not sticking to the initial target.

Is this some sort of bug or the way "classic" pets are supposed to work? [You must be logged in to view images. Log in or Register.]

It's kinda retarded, since my SK pet has like 5hp and dies really fast once it gains aggro.

Example scenario:

I pull two mobs via a bow
I DoT mob A and send in pet
At some point during the fight with mob A, pet decides to switch to mob B
Pet gains aggro due to damage > initial frenzy hate via pulling mob A with bow
Pet dies

WTF
