I got this idea while posting in another thread, but here it is:

Spell components have always been kind of an awkward system in this game, but what if there were SUPERIOR spell components that, say, added spell duration or damage or maybe even a secondary spell proc? Or maybe just increased caster level? I think there would be some cool things that you could do with superior spell components that would be pretty fun and interesting and make this sideline system more rewarding.
