I think that when you use a sun spell helper such as gargantuan or monstrous that when you cast that spell in battle the symbol you cast should be a sun symbol instead of the school's symbol of which you are enhancing. The sun spell symbol in my opinion is not used that much and i really like it. Personally I would like it to do so to show off that I know sun spells! I have only seen the sun symbol being cast when a mutate or cloak is being used and I think it should be used more. So once again when you enhance a spell with a sun spell the wizard should cast or form the sun symbol for it. :D
