Impossible. Literally anything would be an improvement over yet another story about an ancient evil threatening the world with you being the last in a mythical line/chosen one/special dude and the only one with the power to stop it.
Even a piece of [censored] story with no conflict conflict, effectively made up of a bunch of barely-connected episodes, that waddles around without any sense of direction 80% of the time? You're right, though, at least it didn't involve any ancient evil you had to destroy...except for that

"Original" does not automatically equal "better" or even "good." And DA2's story can't even be called original either.
Not addressing problems is stagnation, not regression. It's certainly an issue, but it doesn't indicate any amount of simplification over it's predecessor. And really regardless of whether or not you believe the updates made to ability progression were good decisions, it was undeniably more complex than that which was present in Origins. The ability trees were far from perfect, with some requiring you to select mostly useless talents just to reach something worthwhile, there is definitely more depth there than in single path progression.
I said that they got worse. They were not only not addressed, but simplified areas indirectly affected others. Every encounter in DA2, for instance, is quite the same; enemies spawn in waves and attack from every angle. Every. Single. Time. Less thought was put into them than in DAO, and the same strategies only ever need be recycled even more. DAO was guilty of this to a degree as well, as it often threw the same enemy combinations at you, but it at least had the occasional varied fight that forced you to switch gears. Furthermore, positioning became even less important in DA2 thanks to characters being able to swiftly cross the battlefield in an instant, and for friendly fire being removed from all but the highest difficulty levels.
Ditto for itemization, which got worse for two things. For one, they simplified the mechanics of the original by making it so that only Hawke could equip armor, and two, still made the majority of drops absolute trash. Armor was included with the drops. Armor often intended for one class...that only one character could ever equip. Put two and two together at what this equates to.
