You know, I'm starting to think that for many people, DA:I falls into a kind of "uncanny valley" of game design, in the sense of being almost but not quite like Origins is far worse than not being like Origins at all. Because while some things have changed compared to DA:O, they're still fundamentally very similar games, the changes are really minor on an overall scale.
Overall I think the changes combined add up to a game that is very different from Origins.
A few examples:
In Origins we had ability points that mattered at each level up, now they're hidden away in a long list 'cause they're not important 
We had 80 spells, now we have 20 
We had 40 quickbar slots, now we have 8 
We had 200+ different condition settings for tactics, now we have what, 10? 
Dragon Age has been streamlined so much I can hardly recognize it.
That's not to say I find Inquisition a bad game, but if I were to rate them I'd give Origins 9.5 /10 and Inquisition 8.5 /10, mainly because of the differences in the gameplay mechanics.
