Peoples are just throwing features into the ring that make no sense from a game design perspective to be disappointed. In a linear story based RPG you want lighting etc as part of game design to establish the mood of a scene. I am equally furious now because I don't have Force Feedback on my console controller when I crash vehicles into the wall while driving a horsecart in BG3.
You realise BG1 & BG2 had a day & night cycle right? People are various degrees of non plussed or dissapointed, but there is a reason.
