I really enjoyed the map voting system.
I have found that game modes like Warzone really point out how much i miss this the most. There are some Warzone maps that i would rather just not even play, especially when that followed by a Warzone map i'm not fond of, but not passionate about either. That's 30-50 minutes of gameplay on maps i'd not amped to play on. If there were a voting system i feel the best map usually wins. If people complain about the 1 good map being picked all the time, then it means resources should be focused on creating more good maps, instead of just creating maps to populate the players options. Games modes that are much shorter like SWAT this isn't such a necessity but i've gone more than an hour playing Warzone maps that don't entertain me, and it's a big reason why i stopped playing the playlist,
