I don't know about that. Each of the "origins" had something happen immediately before you got the "main story/problem". To say that it is the same seems kind of odd.
I believe the issue is that DAO was geared as the first and introduction to the world while this game is not. You can't have the first "quest" in the first game have some crazy detailed thing where the player needs to start making "big choices" immediately. My memory of all of the "origins" where straight forward "something bad has happened, fix this now" with a later of "oh crap! dark spawns!!" while DAI throw the player into a situation that involves psuedo-politics and psuedo-religion tensions where the player may not know which way is what.
After my first 8 hours of DAO I thought it was pretty generic, had a lot of MMO stuff, and the characters weren't very interesting. The first 8 hours of DAO are not significantly better than those of DAI. I don't think any specific 8 hours of any RPG ever actually give you a good picture of the quality of the overall game. The end of DAO where you're saying goodbye to everybody would have been total crap without having spent the last 50 hours with them. RPGs are cumulative.
