@VOTChaos1) I don't know about all maps being darker, but I do know they attempted nightmode maps, and boy did they fail. Sure, some people complained it was too dark, but obviously they don't live in the woods like I do where there is no light. The maps they used were effectively woods maps with the amount of space between buildings. The natural lighting should have been way darker to be more realistic.
2) Extra points for eliminating a higher rank player would be nice. Maybe reduced point loss for being killed by them?
3) Solo can que separately from other duos by hitting the "no fill" button. Solo queing entirely. Don't know if that can be done in ranked though. Some special modes don't let you soloque, like Revival.
