I'd rather have DA:I mechanics than D:OS2 mechanics. In fact, DA:I mechanics would be quite nice.
Hmm. There was a great deal about Inquisition that I liked, but its mechanics isn't really one of them. Especially the likes of boss battles with the ME-style repeatedly regenerating shields whose only purpose was to prolong a combat encounter I was already not enjoying. But perhaps I'm just a habitual malcontent.
