Divine might be a little broad for me. I wouldn't mind segregating out the farsensing/info gathering spells and the space/time being spells into their own category.By the way, please "quibble".
Likewise, I might break up Animal into beast and nature spirit spells and body affecting spells. Venom/corruption could also be its own category.
Obviously, perfect parity is impossible, but Plant and Illusion feel like the right "size" for a targeted spell list.
