Isn't this the FPS where it is better to stand still more, than move and be spotted? You do have to travel a lot for sure on such large maps, but when there is any sign of closer engagement, hide in a bush.
I don't like the "realism" of not being able to identify friend or foe at any substantial distance, but I guess some players prefer that level of realism. They have friend markers, I just wish they would work on a timer at aimed distance, or you had a q-spotting system like Planetside 2.
