Larian are not communicating anything back other than "we listen to feedback". If they would be explaining their design choices or goals better, especially when deviating from D&D rules, perhaps testers would feel more encouraged to play and give feedback.
Larian are also not saying what they especially want feedback on. Maybe your feedback concerns something they absolutely won't change, or something that has already been planned to change.They just said play the game and we will gather data. I don't trust their data analysis because players might not actually like the way they play, they could simply have no choice. E.g. combat still revolves entirely around high ground but that doesn't mean players "like" to play king of the hill or "hate" to use spells that give advantage. They are simply playing the way the game was set up.
And perhaps if they added the missing classes and races and some armor and customization options, and new companions, it would be more interesting to replay from a gameplay point of view. You can't keep replaying just for the same story.
