It is creature light for a Holy Mage in my opinion. I generally run with 40 spell point in creature spells for Holy mages myself. I like the Noble Vanguard, it is good for dealing a blow and then taking the blow meant for your Mage, and it will likely survive for a while on Consecrated Ground. I would also suggest considered a Guardian Angel which, combined with Consecrated Ground, tends to live halfway to forever, though it cannot be combined with Knight's Courage and is not Vigilant.
