Idk about matching the current enspell. It would be extra steps that might be unnecessary. It seems like more of an excuse to get enlight and endark, than to be functional to the RDM.

But i'm very much in favor of the teamwork aspects of it.

Being a nuke delivery system for higher tier casters would be an aspect of RDM I would enjoy and I think everyone else would enjoy as well. I've put some of that in RDM melee... but that thread is super long so ill dig it out and post what i put there so we can compare notes.
