First time I felt like I was playing a battlefield game with the recent Panzerstorm map. We ran across the map, isolated flags, did team work didn't get spawn killed every 5 seconds. It was alot of fun even though I am not much of a vehicle player. What made it fun ? Map size was definitely a big factor. There are 200-300 meters between flags(more in some cases), so when you attack a flag as a squad, you can isolate that part of the map if you play it right you can hold it. They can't just zerg rush it with 15 people at the same.
So I hope we'll get bigger maps like this in the future.
