I never did enjoy the caster system just because of how ungainly it was. Simplicity, modularity, efficiency wins.
Excited to see this, though I probably won't use it. I've always liked the idea of every spells' scope containing absolutely everything that the spell needs to function. It just makes things so much easier.
Either way, more power to ya
EDIT: I hate myself for making this post. Somebody kick me in the face.
