I'm not making my opinion from Google images, I've actually played the demo and the EA.
I guess it depends what you call "verticality". If you mean it's not completely flat, then yes, it has stairs and heights like any other game.
Places like the ruined tower, the fort of Caer Lem, the Dark Castle, the place with goblins and where you find Kythaela are in mountainous environment, so at the outside there are slopes, and sometimes there are cliffs on the border of the map, it wouldn't feel natural without that.
The outdoor of the library (ruined tower) have a couple scaffolds, yes. It naturally blends in the scenery since it's an excavation site in the middle of the mountains. But you don't have to climb them up and down, though.
The terrains of random encounters are similar to any other CRPG and pretty flat, if you can that a vertical puzzle then indeed, we are not playing the same game
Even Doom had more vertical features than that.
Then there are a few areas where they exploit the vertical dimension. The library is one, they went very creative for sure, it's a puzzle and it's a bit crazy. That's the example I showed in my preview, by the way. Sometimes there are high-placed enemies to ambush you, like when you escape the Soraks in Caer Lem IIRC.
It is one of their selling point, and they made it well known so it's hard to criticize - if you don't like that, just don't buy the game. After the demo, I thought they'd actually put more "3D rooms", but it's really not that frequent, they even removed the one of the demo. Most of the time, it's natural terrain, forts and dungeons.
I just don't see what the actual problem is with heights, sorry. We'll have to agree to disagree on that one, to me it's actually funnier when it's not flat
