The more I read the comments in this forum the more I get the impression that all Larian Studios is going to do is put D&D skins on a different game so it will look like D&D, but it won't play or feel like D&D during encounters, and so it won't really be D&D.
Have you ever actually played D&D? I don't mean D&D as manifested in games like BG1 & 2, but actual table top D&D?
