Game Mechanics: Pet aggro

[finalgrunt]

I've noticed this recently, a pet sometimes doesn't aggro a target as it should (it has changed, wasn't the case before).

I've seen pet dealing more than 200 melee damage and having the target still running at me (with me doing nothing). And sometimes in the same situation, a single attack is enough (less than 40 dmg).

Also, pet spell damage doesn't generate threat.

It's rather important for a magician who relies only on the pet to tank the target as soon as possible.

And I reread all the patch notes, didn't see anything about this.
