I want you to know that you're not alone
Despite we didn't talk much, I want you to know that I agree with you about enemies in DA2, you're not alone with your views. In Act 3 enemies were to choose, mages or templars since the begining. Orsino is only the one Hawke have motive to stop, because he supported Quentin, but it was revelated only in the end of the game. If Hawke knew it earlier, then he wouldn't look like a mere templar supporter, but a seeker of vengeance for making him an orphan. That would be a good againt the anon that recently replied to you.
