^ There also hasn't been a wide-spread mage rebellion against the Templars before, either, or a Divine fully and utterly committed to change (either Cassandra or Leliana). Like other posters have said, Cassandra is giving mages more freedom - gradually.
I sure am glad you've posted that Far Cry graphic, though! Completely changed my mind.
"The fatal poison of irresponsible power was already in her hands, and soon commenced its infernal work. That cheerful eye, under the influence of slavery, soon became red with rage; that voice, made all of sweet accord, changed to one of harsh and horrid discord; and that angelic face gave place to that of a demon. "
Absolute power corrupts absolutely as they say. Cassandra reminds me of Frerdrick Douglass' master's wife.
"Slavery proved as injurious to her as it did to me. When I went there, she was a pious, warm, and tender-hearted woman. There was no sorrow or suffering for which she had not a tear. She had bread for the hungry, clothes for the naked, and comfort for every mourner that came within her reach. Slavery soon proved its ability to divest her of these heavenly qualities. Under its influence, the tender heart became stone, and the lamblike disposition gave way to one of tiger-like fierceness."
What was her first response when the mages of Redcliffe were entrapped by the machinations of Magister Alexius? Was it to be understanding of the situation, that they were used and manipulated? No, it was mass conscription and imprisonment which is hardly justice. Though she spouts out noble ideas about trying to improve the welfare of the mages, her impulsive reactions showed to me that as soon as the mages start doing wrong, it will turn to resentment that will color the entire mages and her responses are harsh. Even she herself is known to acknowledge that she is not always right and she is impulsive to a fault but not after much reflection later. We don't how well she improves mage livelihood, but she's known to make concessions. I almost think Vivienne would be a better alternative to her, as even though she's in it for her own power, at least the circle mages are allowed more freedom and responsibilities. What we hear of Cassandra's reign as it is in the epilogue is it divided the rebel mages and caused a civil mage war between College and circle mages. And when siding with the templars, she's forced to compromise and could possibly lead to violence on sects who oppose her reforms meaning that her gradual changes are easily reversible if those subversive sects still exist. Cassandra seems like someone who only knows to hammer something bad, and lacks the subtlety to change the hearts and minds in order to have the populace accept her reforms. She's like Harrowmont, the traditionalist that seems like they'd get something done due to their military background and supposedly honorable demeanor, but is completely wrong for the job on account of their headstrong brash ways.
