People need to stop fussing over Leliana. Mage freedom ending was leaked a year before the game's release. It wasn't rushed, it was always meant to be part of DA:I epilogue. I always saw Nobles to be more dangerous than mages and they would roughly be the same number and they can have more power than mages. I mean the south is ruled by tarts with fancy crowns who think they are better than anyone else and they think they are more able to rule the masses than mages. I'm not suggesting mages should rule Thedas, but you gotta admit magic is not the only power that's dangerous. If you fail at politics at the ball, the game is as over and Corypheus wins. That's the power I'm talking about. Not even the strongest magic can cause that.
Mages can police themselves. You make Leliana Divine, side with Mages and encourage Cassandra to rebuild the Seekers with better ideals and goals. Templars will become seekers who can be called upon for anything as the order now stands for "Justice for all" and that includes the mages as well. This whole rebellion proved the old system didn't work and the paranoia that mages might become possessed killed as much as all mages becoming possessed all at once. The issue was not as small as leashing Templars and giving slightly more freedom to mages inside the circles. That's how the circle were at the beginning! Read the WOT people. Then the chantry and templars started cracking down harder until mages were needed, like in a blight. After victory they were given more freedoms only to be taken away again later. Not to mention a circle like Kirkwall's was allowed to exist.
The way it sounds the new seekers are ten times better than any epilogue for Templars. And with Leliana they get the highest number of recruits.
