RP for mages that are FIRE or EARTH heavy is great atm. You can take on the appearance of those elements. It would be neat if the other elements could be represented in the ritual spells if not with their own spells/aspects than maybe with a cantrip that can change the visual of what is in place right now...or maybe a meta spell.

The spells would do the same thing and the Aero/Electric/Ice mages could have a little nod as well.
