"Qunari give me the creeps. No one is that dedicated to some abstract ideal."
(10:39)Dohoho, I see what you did there, Ms. Hepler.
Also, I'm basically pro-Circle autonomy, but it's one of those subjects where I have a lot of thoughts and not really enough of them are coherent. I understand that mages are dangerous, but I don't believe that being dangerous is sufficient grounds to restrict them of their rights. On the other hand, the Circle as a means to teach younger mages how to control their magic and protect themselves is a good thing - it just becomes less so with the whole CONSTANT VIGILANCE thing and taking away the rights of mages to try and function as normal human (and elven) beings. It's kind of reached the point of a self-fulfilling prophecy. The Chantry perpetuates the idea of mages being demons waiting to happen, everyone else responds in kind, mages have fewer and fewer rights and the prospect of having the power to fight back by any means necessary becomes more and more appealing, then blood magic, blood magic everywhere.
But
then you have to consider whether there is something to Fenris' "mages will make themselves magisters also I am handsome and brooding" schtick, because it is demonstrative of how the power mages possess can make them effectively unstoppable forces
because they use that really annoying barrier where you can't attack them at all whilst they summon a bunch of mooks for you to fight and only dispel magic will stop it. I don't think it's an inevitability - it only happened again in Tevinter because Tevinter didn't know how to work otherwise - its foundation was based upon slavery and mage dominance, and it was much easier for it to fall back into its old ways. In the rest of Thedas, I think if the newly freed mages seemed to be getting too big for their boots they'd be killed outright.
Alternatively: DA3; everyone becomes a mage, mass hysteria followed by an orgy. Problem solved.
