I know its a long shot and that a lot of people think that it would just make it harder to "Have fun" but i think that with the new tileset, night is a thing that we can think about again.
If you go offline, and type .time 0 00 0 that is the average lighting of night time. type .time 5 30 0 that is the darkest time of night.
If i am correct, the reason that we got rid of the night was because it was to hard to see. Well i think its easier to see now at night than during the day. Theres no way that you can get snuck up on anymore, (if your watching the game and not AFK) Its not any harder to see icons at night is it? last i checked the default yellow red and green weren't hard to see.
These Screens are as dark as it gets.
And these are normal night.
If they appear really dark. try saving them and opening them full screen.
