I hope the map designers provide more cover and accessible areas in buildings. All the maps they have designed are so opened and made bare when everything is being destroyed. If you plan to have vehicles and helis, you need to design it with sufficient cover for infantry to hide and move forward. May only be a game, but as realistic as it is, no one goes into battle in an open environment full of helis blasting the ¯\_(ツ)_/¯ outta you from the top.
Also...remove those damn thermal optics!
