This macro works mostly but sometimes it cycles through then loses target completely.
/targetenemy targets 1st on agro list
/assist <2> targets tanks target
/ta <attack5> targets 5th priority target
/ta <attack4> 4th
/ta <attack3> 3rd
/ta <attack2> 2nd
/ta <attack1> 1st

Is it too much? I think the attack# is whats messing me up cause it only seems to fail when the tank does use priority marking, and I cant find documentation on it. But the post that recommended it seemed pretty real. Is it valid or should I just delete those lines?
