It is situational..... some fights and cicumstances will call for Light others Wisdom. There isnt a right answer here. One of the things i LOVE about pallies is that we have so many spells and so much functionality given the situation.
Go with what is right for you given the situation you are in. If your healers are having a hard time keeping up and you need to smooth out healing, do Light, if mana is an issue and its a long fight do wisdom, if you have other pallies with you then coordinate things to maximize the use of all spells.
