Not trying to be a smart ass, but night is pretty cool. Everytime I log in and it's the sunset time or night I curse, because it means I will not have a fun dogfight (icon chasing not that fun).
In the other hand, night/dusk/dawn allows me to switch to a different mood and it's usually bomber time, tank time, sneacky base capt time. I like to plan/use the cover of it.
It would be great if at night icon range would be lowered to 1K, making the use of radar night fighters a must have. It would be a fun way to introduce them and make people fly them.
