How would you feel if there was an added pet option that would set Eos/Selene to follow your targeted ally (party only) much the same way she does with Heel to follow you? However, it wouldn't affect your abilities of using the pet skills like Fey Union, Rouse, WD/FW, etc.
I've talked to a tank friend about it and we generally laugh at the thought of Lily flying around his head while he's buster swording in all his dark vengeance.
