Bug description: Pets do not seek their target's backside automatically.

Code:

Shortly after the Greater Earth Elemental is activated and starts attacking, it will move behind the target, and prefers to attack from there, assuming it is not tanking the target itself.

Generally, all pets should automatically seek their target's backside and remain there UNLESS they are tanking the said target. This could solve the problem with pets getting parried/dodged, should that happen.
How it works for us:

All pets just cluster in the direction closest to the target and start mauling it.
