Guys I know i'm well late on this thread but listen up anyway, If we where flying as USAF, RAF, Luftwaffe instead of Bish, Rocks & Knights then you would have a point about the non icon thing, I say this because you would be able to tell the shape & colours of the planes ( Spitfire, 109, FUF etc), but even then it would not be a good idea as ah graphics are not that great & you would have to get D400 to see what plane he was flying anyway.
I was always wondering if the game would be better if you had to look at the plane for a period of time before you saw him high lighted, but anyway I like the game how it is so no chasing the dot for me.
