I would have liked for the other mage in Redcliffe, the pro Tevinter woman, to be less of an muahaha caricature and actually make good points about why southern mages should go to Tevinter. Maybe make it look more reasonable for the mages to have agreed to the deal (since they didn't know it was actually Venatori and not the Tevinter government).
Or don't make Alexius look so unreasonable in changing the terms of the agreement as he went, and when Fiona says children and elderly shouldn't fight, he could agree and say they would be kept safe to show Tevinter's good will.
I wouldn't have minded for there to be someone who espoused that viewpoint. I mean, I don't even disagree with the deal on principle "You hate us, don't want us here, we're trying to leave."
But it's perfectly logical for there to be a good number of mages who are just looking foward to being part of the upper class when they reach Tevinter.
One thing I did like was the contrast between Lysas and that other black mage you can speak with near the Gryphon statue.
Lysas is vehemently pro-freedom, going so far as to think of the Circles as slavery, but he doesn't seem to be that bad a person. Kid wants to grow crops and have children and in the Bad Future, it is revealed how he actually didn't break and join the Venatori.
Meanwhile, that other mage is the definition of groveling, all but throwing himself at the Herald's feet and condemning Tevinter in the harshest terms. But in the BF, he has become a Venatori and tortures the pro-mage Cleric that is near the Chantry showing that he was just telling us what he thought we wanted to hear and quickly went along with whoever was the dominant power.
And then there's Connor and that other mages who saw that mages are a threat and actually liked the Circles. So, there were many viewpoints available.
