The Wardens arc was a wonderful story: pulled from the life you knew to fight an ancient, unholy enemy. Unite various cultures and factions in the land, struggle with politics and intrigue, build an army, become Kingmaker, all to push your efforts towards defeating the Blight and saving an entire nation.
Hawkes story had none of that ambitious drive, really.
The Wardens arc was a generic high fantasy story about a young hero/ine whose normal live gets interrupted by tragedy and then is pulled into a battle against generic evil hordes of more or less mindless monsters that are lead by a generic evil overlord that wants to destroy the world because....he is evil I guess.
Along her/his way s/he unites various cultures, solves problems, everyone else failed to solve, with ease, struggles sucessfully with politics even though (most) of her/his origins never had to deal with politics before and becomes Kingmaker even though it completlely defies logic (A random elf from the surface and the local drunken clown tell us some crackpot story about a long dead smithing-paragon wanting them to elect our king? We better accept their flimsy evidence that is basically just a fancy hat. Well at least Behlen is smart enough to call you out on your nonsense.)
But the whole thing was executed in a perfect way, which is why it was such a great game.
Hawkes story on the other hand has no ultimate evil to defeat. It is a story about a gal/guy who tries to buil up a new live and gets sucked into conflicts that s/he has no chance to solve on her/his own. Conflicts that arise because of mutual hatred on both sides for the last decades. And unlike the Warden Hawke can't just handwave these conflicts away because Darkspawn is going to eat everyone if they don't work togehter right now. Sometimes bad things happen no matter what you do. DA2 actually showed that sometimes a single person can't make a difference no matter how badass they are.
It was a pleasant deviation from the typical Bioware power-fantasy where everyone grovels in the dirt at your feet and whorships you as the wisest person of the world after you either pass a persuasion check or kill something. I personally liked it and think that it had the better story of the two DA games, even though I still think DAO was more enjoyable overall.
