i dunno about lower levels as i was lvl 50 before i got our personae.
but my pet never was and still is not able to hold agro against me (unless i really hold back).
however since they changed our pet spells and gave it they ability to root and stun more i dont have that much problem with agro and the mob coming after my anymore. not because i wouldnt be top on agro list, but because the mob simply cannot move.
