In my opinion, the fact that the templars are wiped out is an opportunity that we should seize, because I don't know if it'll come again. And mages will still have their own society under Leliana; it should accomplish everything that you want.
Well, not really. I'm more in line with a Wynne or Rhys view on the situation (a moderate conservative?). My personal view on the Mage-Templar debate is this:
- Mages were, for the most part, not being abused prior to Anders terrorism; while they had restrictions, there were checks and balances that allowed mages who earned it, freedoms away from the Circles
- Templars were, for the most part, not abusive; most were just typical soldiers who were doing their jobs
- However, due to the corruption of the templar order in some Circles, a mage rebellion (Circle Reform, would be better) was necessary. Anders terrorism caused more death than it helped prevent and, I agree with Vivienne, the timing of the rebellion was terrible because of this.
- Whether a Circle is necessary or not is up for debate; while there are societies that don't have them, all societies had their own checks and balances; all of which had pros and cons and none of which seemed better or worse (okay, the Qun makes it worse)
- I don't think that the Circles need to be destroyed; I think that they need to be reformed with mages having more power and control and templars being more closely watched for corruption; Circles should be less of a prison and more of an academy, but mages still need to be watched for possession in some capacity
So for me, Leliana is the worst Divine. I think she's all idealism and she will single-handedly cause the death of thousands of people, both mages and commoners alike, by failing to institute an appropriate checks and balances system. The mages can't govern themselves, in my opinion, because absolute power corrupts absolutely; her reign will lead to the rise of a new Imperium.
Vivienne's reign is better, given that she does offer a better situation for mages than they had before; she reinstates the Circles and gives mages freedoms and responsibility, while still maintaining a Templar order to provide that check on mages. However, the power pretty much all rests with her. This is a band-aid fix; it covers the wound, but doesn't heal it. Once Vivienne dies, will her reforms be sustainable? I'm not so sure, particularly if they put a non-mage in the throne after her.
Cassandra's is the one that I like the best, but that's only because of the character, not the wording in the epilogue. Based just on the epilogue, it sounds like it goes back to status quo (more so than Vivienne even), but having discussions with Cassandra, it's clear that she's interested in reform, not just restoration of the orders. She puts the Circle back, puts the Templars back, and reforms the Seekers. And if she has strong approval from the Inquisition, it's called 'a golden age' (the only epilogue slide to do so). To me, this is the most sustainable and long-lasting situation that will provide security and safety for everyone.
