Actually, Ferelden is grateful because it gets rid of the mages more quickly either way. It's only Teagan who gets annoyed, and as we see from Trespasser, he's become a giant douche anyway. Finally, any mention of "time bombs" is strictly hypothetical, since they never cause any problems for the Inquisition thereafter.
I'm sure Ferelden is happy to have the mages leave, but it's still political egg on the face of the ruler(s) since a rogue organization squatting in contested land enters Fereldan and invades a castle without prior approval. Yes, the ruler(s) grant permission at the end of the quest, but the Inquisition didn't know that would happen when we went into Redcliffe castle, that's a lucky coincidence.
I don't think time bombs is an unfair description, since if we conscript the mages, some of them later flee Skyhold and try to rejoin other rebel cells. And they damage Inquisition property on their way out. That also doesn't improve the Inquisition's image if it looks like it can't control the troops it conscripted. Granted, it's a cosmetic consequence and doesn't actually have real effect, but that's the same with the majority of decisions in the game.
vbibbi, I will never ally with the Templars for what they did at VR and the way they couldn't wait to kill all mages even those that had no part in the upraising and remained at the Circles.
The Templars are the real cause of the mage rebellion since they have raped, tortured and killed mages without just cause simply because they could while the Chantry looked the other way while chanting the Chant of light in their self-righteous glory .
I agree that the templars are one of the main causes of the rebellion and in no way support them as an institution. But in DAI, I felt that their quest made more sense than the mages' and like Barris more than Fiona. I know that Bioware intended for the mage path to be the canon one, as it flows better in the story, but I can't ignore all of the poor writing involved in it and all of the mental gymnastics required for it to make sense to me.
