This. I don't follow the beta-testing here, just came to read the RC notes and saw nothing on lightning and I'm disappointed.
If you try Chernarus for Arma 3, the lightning is completely broken and there won't even be a proper night. OK; maybe it's up to the custom mapper.
But it also affects a lot of things in Altis and Stratis too. For example, the car lights are too small now and you can look into every light with nightvision on. Before, having nightvision on in city district with lights was a big disadvantage. Now you can look directly into car lamps.
