Can't speak to the other games you brought up (since I've never played them), but I feel that if Metacritic and Wikipedia classify it as such, they're just confused about what an action game is. And while Dark Souls is an action game, it's hardly the one I'd be name-dropping as where they come from - more Devil May Cry or God of War. Hell, for action RPGs the grandady is probably the Tales franchise, at least as far as series I'm aware of go. Maybe Kingdom Hearts if you think of that as an RPG.
And yeah, we definitely disagree about the latter. Dragon Age 2 is in no way focused on "action." There's no action-oriented gameplay going on at all, none of the mechanics that define that style of game involved. Whatever you want to call it (I hesitate to call it a "tactical" RPG either, since in my mind that moniker goes on games like Fire Emblem or Disgaea, with grid- and turn-based systems), it's a totally different beast from action games.
Also, enemies "die almost as soon as you look at them" in DA2? Did we play the same game? One of my bigger complaints about DA2 was the ridiculous health bloat on enemies that caused even smaller encounters to drag on longer than they should have.
Precisely. Mechanically, Dragon Age 2 plays exactly like Dragon Age: Origins, just with some rebalancing of abilities across the board and the addition of cross-class combos. Visually they tried to make it look smoother and more like action games, but the underlying mechanics of the two are identical. Without question, they should be categorized the same as far as genre goes. Inquisition altered slightly more, but not much, and what it did change didn't make the game more action-RPG-esque.
That would be great, I'd agree. I'd worry though that Bioware themselves may have a different idea than I (or others) do about what the strengths of each game actually are, though. If they decided that the strength of Inquisition was the open-world areas full of junk that's need for the crafting system, for instance... well, again, I skipped Andromeda, I can skip a Dragon Age if it doesn't sound good.
