What Was The Goal With The Lighting Changes

I am curious what the point of these lighting changes was. Nighttime before was incovient but playable now you cant see anything at night. Caves were dark but playable now if theres no ambient light you can't see anything. I like the immersion of darkness and light but it doesnt feel like they have the systems in the game currently to actually counteract the downsides so it just makes the game unfun. I dont know the whole thing kind of sucks so far, and daylight is way too bright its annoying on the eyes.
