The opposed schools aren't completely random. I suspected this was the case and drew up a chart to confirm:
If anyone wants to have a robust discussion on what should be moved where, now we can do so more easily.
Well I cant speak for others but when I said random I didn't mean there was no pattern to how they were selected for allied and opposed just that the logic underlying such decision was suspect so to quote myself I do it like this.
Main School: Allowed Schools
Conjuration: Illusion and Evocation
Evocation: Conjuration and Transmutation
Transmutation: Evocation and Enchantment
Enchantment: Transmutation and Illusion
Illusion: Enchantment and Conjuration
The main school should define which other schools get selected based on its mechanics. So Conjuration is summoning things that weren't present not modifying things that are already present. Ergo Conjuration gets Evocation and Illusion because it summons them much like creatures or items. The elements for evocations come from somewhere else as do the illusions. Transmutation and Enchantment are banned because they are about modifying things that already present. Be it matter or minds.
Evocation would get Conjuration and Transmutation because its about manipulating energy in this case to create items or creatures or to modify existing creatures. Energy is Matter after all. Whereas Illusions and Enchantment are banned because Illusions aren't actually anything physically and minds are more abstract as well.
