Freeing the Darkspawn of the Call and giving them sentience was (is?) the Architect's goal... but the whole issue in Awakening is that The Mother and her followers, once "awoken," all went violently insane without the archdemon's Call. So I'm guessing that, if even sentient darkspawn can be driven mad without the Calling, non-sentient darkspawn don't stand a chance.
It's possible that the Architect can work on a solution for that, but it'd certainly be a different situation then if all darkspawn just suddenly stopped hearing the Call.
Well yeah, as I said, they have the full range, including insanity.
But the Architect did have quite a few successes, I mean, he manages to basically build a small army with free darkspawn that both support him and didn't go insane like the Mother did. I'm not saying it's a perfect fix, but the possibility is at least there - at the very least, the darkspawn would lose their cohesion as a single-minded group. I mean, the single thing that makes the darkspawn so incredibly effective and makes the Blights such a huge threat isn't necessarily the darkspawn themselves, rather that they work as one mass following the given archdemon and they rely on the archdemon's intelligence. But if there wasn't a single mind controlling them... divide et impera.
Well anyway, I'd be interested to learn what would happen if the Calling ceased - at least darkspawn can be killed, unlike the archdemon, so the GW's might only be needed in a regular soldiering fashion, being immune to the corruption.
I'll go back to Syndicate now.
