But really that doesn't matter in this thread, which was about 'can an arcane caster heal'. I mean, there's a better arguement in my opinion why arcane casters cannot do necromantic healing than how they can't do conjuration healing. And the arguement about positive energy healing and negative energy harming is more strongly supported by the fact that healing is now in conjuration. If you're using necromancy to heal with positive energy, you're manipulating the energy in a specific way that allows healing. If, on the other hand, it's just conjuration, then ANY positive energy will heal (and, as pointed out, massive doses of healing will harm).
