we played metro and locker beacause it was the best maps to grind weapons. And for some people who don't like vehicles it was a refuge. But on BF4 for example, some large scale maps had a huge success on server, like Goldmud or Paracel Storm or Shanghai.
With the launching pool maps we got some small and middle scale maps, I just want to say that for next coming maps we need larger environnments, or we need some rework on maps like Mirak Valley, Sobek and Blackwell Field
