Why not continue the Wardens? What do Wardens do between blights? Can they be an organization for good? Perhaps your character is a catalyst for change reinvigorating an ancient order? I mean you went from being superheroes to a totally forgotten and irrelevant order over night. Then the world goes nuts, there's a rift in the sky, demons rampaging around the land, the Chantry collapses the mages and templars go to war do the Wardens just sit on the sideline and watch the world decend into chaos? Is there resistance in the Order about taking action? From outsiode the order? How powerful is your blood? How far will you go with research into the power contained in your blood? Remember the demons of the fade aren't familiar with Darkspawn blood and it's powers, it's alien to them. Making the Wardens a demon hunting force to be reckoned with. Why the hell couldn't the story continue?!?!
There are lots of ways you could have continued the story in a cool way without making 3 disjointed games. This is the reason I still play Baldur's Gate so many years on, it flows soo nicely. Everyone seems to have forgotten how to make games recently. 
I just- I can't fathom how they took the design choices they did and ended up here?!
Did they sit down and go 'You know what needs to go? Stats, and their progression. It's to confusing people don't understand how to manage Willpower and Strength and all that jazz, just drop it entirely and use "perks" '
