If there is one thing I'd like to see more of, it is the allowing of mages to pursue other interests that might benefit society, particularly like that of healing. I would like to see mages provide healing services, both to the poor and maybe even contract out to noble families. The proceeds would go towards the upkeep of the circle. I would like to see mages possibly provide other services to the public as well, perhaps in something like construction, perhaps even work at the behest of the state, if supervised by Templars.
Iirc, WoT says that mages were limited to what they could pursue during the early Chantry and before the Circles. They pretty much did healing and Chantry flame maintenance.
Not much healing now, which isn't that strange since there are doctors/surgeons out there and mages can't cure diseases, just encourages the body to heal. Again, iirc.
Still, regardless of others being uncomfortable around magic, a broken leg healing in a day is better than not able to feed one's family for a week. Ander's clinic was popular.
On another note, even if there is the College and Circle, now that the Chantry can't threaten nations to back off, what's to stop nations with enough resources to make their own schools with greater or fewer restraints on mages? Nations now are not obligated to tolerate the Circle or College.
If I ruled a nation or city-state, I would immediately seize Circle land and resources. That stuff is valuable. I could also make the Circle or College pay taxes and agree to free enchantments if they wish to have influence on local mages. I'm guessing BW is not going to do this and just have nations work with the Circle, College, or both.
Really, though, Nevarra needs neither. Just have the Mortalitasi take over with training mages and have no foreign influence on their mages.
Edit: Who is protecting the Circle and College if they are now independent? Can a nation attack and take over a school within their borders? Able to take mages they claim are criminals from a school? The schools are at the mercy of the nobility, now. Annulments can be done by the local lord, no need to have a Grand Clerics permission now.
Just as alienages get purged, so can that happen to the mage schools, now.
