I don't see mages as criminals simply for being mages. Also, it's not stated that the College of Enchanters is created in isolation; it's stated the College is aimed at bringing solutions to age-old problems.
Considering that the Chantry has dissolved the Circles, I imagine some families would be far more accepting to take their mage relatives to a positive environment where they can safely learn to control their magic than the Chantry controlled Circles.
You and I have drastically different views on what Vivienne would do as Divine.
I have more confidence in Leliana myself. A hero of the Fifth Blight, a supporter of reforms for non-humans and mages, someone who will dissolve the prohibitions against non-humans becoming members of the priesthood and who can persuade naysayers into accepting her reforms (assuming her personality wasn't hardened).
Only now, you are saying more lies than expected. The Chantry dissolved the Circles?? When was that?.
1) - When I said criminals, I was refering to how the mages are viewed now by everyone. People were scared of mages before, now they are all along the streets moving around your compound with an obviously uncontrolled templars... Even to remember a terriorist like them mages destroyed the only place people visit to maintain their faith to the Maker.
I'll love to associate this to real life though but I'm out of conclusions seeing we are all living in a chaos much more worst than this game.
2) - OK, And also I will love to support Leliana as the divine since she was my hero in the fifth blight as was Sten, Wynne, Alistair, Morrigan, Zevran.
But let's accept the fact that her ways is far more condemned and corrupted OR Sorry let's say changed by what happened during the fifth blight.
The Circle is viewed that way because of what we saw in Dragon age II. Yes....
3) - Those elves you say are now open to go to the chantry, do you really think the Chantry are very accepting of people from other religion.. Wait I don't know how to explain this without involving real like religions or maybe it's otherwise.
But just remember what cause the exalted marches. Humans will not accept other races that easily.... Maybe tommorrow you see a former qunari converted into Andrastian wisdom, and he is now with a human in the chantry cleaning the tiles.. who knows. Where will the chantry get all the money to take care of those new converts?...
