I just escaped from the Luculla Mines & I have to say, they were a pretty big disappointment compared to the previous portions of the game thus far. The area itself is visually stunning, but feels railroaded & forced. I especially don't like that you can't get back into the mines proper after you discover the anti-death knight spell. There is no good reason our heroes can't teleport over thigh-high obstacles. There is zero explanation in game or in journal for why you can't get back into the mines. Feels rushed or that there was a lot of content cut for this area.
Just my two cents.
