I think as well Bioware is going to move on from the mage/Templar debate but at the same time I think this is a mistake BECAUSE it is what separated Thedas as a setting from your bog standard fantasy setting. If magic is no different than say Elder scrolls magic, how is the setting different from any other standard fantasy setting?
I disagree that the low form of pew pew magic is the only thing that sets this universe apart from others. There's a lot of unique lore involving the known and unknown history of different races, the politics and war history between the known and unknown nations and territories, the high magic in the form of archdemons, Blights and darkspawn, demons, spirits and the Veil, how a lot of that history and high magic tie back into the different religions and credos in the world, how those credos shape socities, etc. Just like the pew pew gameplay magic is not what sets Elder Scrolls apart, but the borderline ridiculously complex system of divinity and how it shapes that universe into existing and not at the same time.
What set DAO apart from other fantasy games of the time was not the magic debacle, that wasn't even a big issue until DA2 made it into one. The Circles issue there was a side subplot, peripheral at best to all the other complex issues the world presented, until DA2 brought it to the foreground and made everything about mages and Templars, at the expense of everything else that is unique to the universe (so much that bringing back ancient darkspawn, the Dalish, the qunari and the dwarven caste system in DAI felt a bit dissonant at first, because we'd lost track of those discussions by that point). But we don't have to stay stuck in that pointless loop or circular arguments about this one subject alone forever, there is a lot more that is unique to this setting that we can turn our heads to, give the same importance and make the new debacle of the week in this universe.
