Yep, folk are welcome to give feedback at any time, including after the game is out!
But I do doubt that Larian are currently scouring the forums for potential changes to the game that is releasing in just two weeks, so it's better to think of sharing impressions at this stage being more of a conversation starter with other community members.
I'm sure past 3 August, Larian will be watching the forums to see what we make of the full game.
(PS I will move this thread to the feedback section)
