And? Avoiding that Wynne was an abomnation and as Asunder showed us she posed threat to others because of that ,from what i recall mages were allowed to leave circle when they had permission ,even in ostagar templars allowed only 7 mages to get out.In first place idea letting mage roam without supervision is silly and pretty much allows mages like orsino to do things they were doing and also endanger society in different ways.
.
See, you're just proving my point. Wynne, the botanist, Vivienne, and the archivist/researchers in Weisshaupt are perfect examples of how to properly engage mages outside of the circle. The problem with Anders, Uldred, and stupidass-Fiona are that they wanted freedom for freedom's sake; the point that Vivienne and Cullen are trying to make is that mages have value in society and outside the circle tower so long as they're able to contribute. The problem prior to the rebellion is that mages have no place allowed for them in society or more importantly the job market outside of the circle; they can't be hired as guards, healers, librarians, researcher, into the army, commerce, etc. This is why Cullen suggests offering mages the ability to join the military services/healing units and Vivienne glows at the idea of integrating them into the chantry; it's because their skills are being put to productive use rather than magic being done and researched... just because.
edit: Uldred was a libertarian extremist, why in the hell would anyone let that guy out?
