Not touchy , only baffled by you pointing something pointless, relying on me saying something certain few times.It is nice to know what words are my favorite better than me. 
There were no circles then, mages were contained and controlled without circles, then circles were created to control mages and protect the world from them while allowing them also practice magic. They only flaws of circle were that they gave mages too many freedoms, what allowed mages to practice blood magic whithin circle and allowed them.In fact, templars tried to put down mage rebelion before it even started and would succeed if not corrupted and foolish divine that decided to help mages start war.
Not rly, a problem to mages perhaps,but not a problem to rest of the world.That mages were abused (what of we have very little examples of despite decent amount focus on circles in series), means nothing to safety of the world.
Im not posting here on that anymore as OP doesn't want thread derailed , so if you want discuss it further create new topic or move it in proper thread.
Oh yes, my mistake. I should have said something more along the lines of the later years of the first Inquisition. But while you are right on the intended purpose of the Cirlces, you are quite mistaken that their only modern flaw is that they allow mages too many freedoms. Several codex entries and a few books detail some of the other flaws in the modern circle system. It is not just connected to the mages. The Chantry and Tempars are just as guilty.
Mages being abused to such a degree is exactly what can cause damage to the "safety of the world" precisely because no one is properly dealing with the issues at its core. The Templars simply trying to force it down with fear and subjugation have done nothing but escalate the conflict to a boiling point that eventually started ravaging the countryside. Templars are a part of the problem.
No one was willing to listen, no one was willing to negotiate, no one was willing to even investigate. The only ones we knew of that were willing to investigate were the divine and a few of her choice agents.
The meeting that preceded the rebellion was at the time, nothing more than a meeting to discuss the implications of the recent discovery that tranquility could be reversed. The divine mostly did this because the Templars refused to let the mages convene all, even though their intended discussion was academic.
It was the action of the Lord Seeker, who intentionally sought an excuse to invoke the Right of Annulment (through looking for only one corrupt mage), that gave the order to plain slaughter everyone. The mages coming to their eventual decision at Andoral's reach seemed expected. The Templars demonstrated an unprecedented amount of undue zealotry with that escapade, and it resulted in the murder of several innocents.
