There was a lot of time spent in making these maps to have choke points, advantage positions and ambush locations, call it what you will I am going to take advantage of every nook and cranny if someone is going to run around running and gunning aimlessly.
People would complain if they made a round map like a barrel and dropped everyone it, trust me everyone in here would say "OMG there is no where to go on this map I get killed in 3 seconds why the hell would they make a round map with nowhere to hide"
