Since the settings of Rivellon and the Sword coast both have European-Plains&Seas&Mountains-medieval art (and that´s all they have in common) I fail to see why they should waste the time of designers and animators to recreate new models and textures for walls, rocks and brushes if they have them already; just because some people think they look like some game they do not like.
Maybe if we´re talking about character or creature design, I may agree, but let´s be honest, if a tree looks like a tree and a rock looks like a rock, I do not think they have to change the model so they do look like less "DoS2".
I think they can spend their time doing other things for the game.
