Woah woah woah woah....woah!
You say dark map with some light mechanics?
I say give us ANY new map. And make it 3v3 or 4v4 map, not made out of other maps.
I mean, I don't mean to be mean or anything, but Devs aren't really fond of making maps at all, so this kind of suggestion seems a bit unrealistic. I'm a simple man with simple needs. Give me maps.
Also, some maps have so many clouds that you can't see anyhing most of the time. You should try the new 2v2 map perhaps.
