It's not nearly impossible. All regular 6v6 players want is 3/4 maps every new season. I don't think that's an unreasonable request. Even if it was 2 new and remastered then I'm sure people would be fine with that.
This season is just a poor effort. 1 remaster and one that was removed from the game to start with. That's just not good enough when the game launched with few 6v6 maps in the first place.
