Magician Pet Aggro

[Meanbunny]

Hey guys, I have a play group with myself, my sister and our best friend starting up. I am playing a Necromancer, my sister is playing a Ranger and our friend is playing a Magician.

What we are trying to find out is, can the Magician pet hold aggro in our group, or will the mob attack the first PC that gets close to it regardless of the aggro level of the Mage pet? Like if the Earth Pet roots the mob, and our Ranger max melees it (gets only close enough to be in melee range) will it stay on the Mage pet or will it turn and aggro her everytime?

Basically just trying to find out if Mage Pets can tank in groups with melee classes and hold aggro. Of course the whole point is that we do not have a healer to heal the Ranger. I would really appreciate it if anyone knowledgeable on the topic could let us know. If a Mage Pet is not a viable group tank at low to mid levels then I may have to roll a Cleric instead of a Necromancer.

Thanks for your time everyone. Have a great day.

TL;DR - Can Mage pets hold aggro in a group with melee classes?
