You were ranting for months about no one finding the Templars credible pre release.
Lo and behold though!
Their still seen as heros.
I think I'm done with your speculation friend.
Unless you dig them out of their mess, they really aren't. Especially not after Val Royeaux.
At least when you do go to Therinfal (and even when you don't, on a smaller scale), the Templars make an effort to correct their mistakes and restore their good name. Of the Seekers, those who didn't meet the fitting end of their treason hid like cowards. They no longer have the numbers or the recognized authority, and that's only among those who knew they even existed. Most of Thedas didn't.
Without Cassandra as Divine and the choice made to reform the Seekers, the Templars will not answer to them again. Especially not under Vivienne.
