What is more important for the user gaming experience in any game, besides the game story itself? User interface.
UI can, and should, be enhanced.
I'll give some very important points, and you can add as well, Larian listens, as we are told, therefore, let's make the user experience better, together.
1. UI is too big, unnecessary big. It all can be neatly placed in a single line (maybe two, rather thin lines), like in DOS:II, the best isometric RPG on the market. Why you want so much to be so "different" from DOS:II? It is the best, so take the best from it, and build on top. Remember UI from worldwide gameplay reveal at PAX? It was a very good base to build on. Just enhance it (there was two lines, but second was basically empty, huge health/movement bars, huge icons of effects on top of the portraits, map was not good, now it's better). Fully adjustable single/double Skills line(s), where you can put anything, this is the perfect UI. Not a bunch of sections, with unnecessary "design" elements.
2. Portraits. First, why do I need 2 portraits in my UI, one in corner (party) and one in the middle of the screen? I see whom I've chosen, I don't need additional clutter portrait in the center. Secondly, portraits now look like it's renders of naked models. Third, add casting spells on portraits. Again, remember UI at PAX worldwide gameplay reveal, there was very neat placement for the party and for the enemies.
Now, what do you think, what are your points you'd want to enhance, let's make the user experience better.
