Okay, so I totally agree that some new maps would be nice, but removing maps like Demon's Breeze is unnecessary in my opinion, since whenever I am in Lobby I see a ton of people voting for it.
Also mentioned were Mortal Skies and Lobby Games, because they lag people. I personally don't get a lot of lag on either of them and it is still playable (my laptop isn't the best either) and I think it would be sad to see those maps getting removed.
However, there are maps that pretty much no one ever plays and I agree that it may be time to remove them or maybe in some cases change the tiering or something. Maps to be removed could be Hub Games (although it is a nice memory, but no one ever plays it), Dracarys, Eye of Horus, Haruka, Excavation Zero and Fallen Empire.
