i actually liked adrian, they did her character very well. She was at least a better spokesman for mages freedom than anders was, she didnt whine as much...
They both wanted to see their people free, and were willing to kill someone to see that happen. I got the feeling that the toxicity of the Circle simply became too much for them. Anders laments the suicides of the mages in Kinloch Hold while Adrian is furious in proclaiming, “If you really fear us so much, then kill us! Don't pretend that killing everything that makes us human isn't the same thing!”
as for wynn, i think they took her character a little off track when she got all angry over them taking ryhs
Wynne has wanted the Circle to become better since Origins, where she tries to encourage Aneirin to return to the Circle, and asks the mage protagonist to become a leader to make it a better place. It's not like she supports the status quo without question. In Amaranthine, she expressed her objection was over her concern that the mages would all be killed if a vote for autonomy were to succeed. She also lamented the loss of her son when conversing with Alistair, so it's not surprising that she would be upset over what was happening to Rhys.
