Take a look at Oblivion. Mages in Elder Scrolls are able to go to their own academies with no mobs. You don't see the mages being lynched if given their freedom do you?
The problem is that TES doesn't have the abomination problem. Yes, there's still daedra worship and the dangers of that, and that did end up being what got the Mages' Guild disbanded between Oblivion and Skyrim, but that's not even close to the same order of danger. You pretty much can't destroy a city with Conjuration in TES unless you're really powerful, and at that it's almost impossible to do without wanting to. Connor proves that you don't need to meet either of those qualifications to do that in Dragon Age.
Just comparing universes is not a good idea... reeks of desperation and i say this a pro-magic fan
If the analogy didn't require ignoring a major difference, I'd have accepted the argument; as it is, that difference is the main reason I support the basic idea of the Circle system in DA where I don't think other magic systems require it.
