Tsuru Reef is probably the worst map in the game

You must be blind if you think it's just '6 people' complaining. Check the forums and Reddit – the community is loud and clear. A lot of us absolutely hate running through empty, open-field maps and lifeless, empty streets with zero cover. There is way too much running and walking around where absolutely nothing happens. In fact, people dislike this layout so much that they don't even want to play Breakthrough mode on it anymore, because the mode's layout and sectors are poorly designed and completely wrong for this map. Forums are made for feedback, and criticizing lazy map design is fully justified. If you like a walking simulator, good for you, but don't act like the majority enjoys this.
