What about the physical aspects of the spells, though? For example, magic bullet uses a small orb graphic so that you can se the center of the actual object. Flaming aura uses a small series of flame graphics. Icestorm uses small clusters of icicles. Summon Elemental spells summon entities that are also comprised of an image. It'd be a royal pain to try and make different elementals using particle effects.
