Just so I clearly understand what you just said. You want to have no idea who is friendly and who is enemy?
HiTech
I think the present icon system is certainly not ideal.
Let me present some of the pros and cons of both extremes.
Current Icon system.....
Pros....Easy to tell friend from foe. Easy to see the name of the friend
Cons..Distance that aircraft are identifiable by specific model is unrealistically high and the same for every aircraft no matter the size or shape of that aircraft. Distance info is far too exact for the period. Huge text based system detracts from visual beauty of the game.
No Icons
Pros....Fights are visually stunning. I've done it, a bunch, in another game and it is amazing how much your brain focuses on the icon. It is awesome to suddenly be focusing on only the plane. This was my favorite part of no icons fights. It was like the best WWII movie you ever saw. Fights were closer, tighter, more intense. Some of the uncertainty of real fights is available. Its a lot easier to bug out of a fight or to actually get a "bounce". The uncertainty of friend or foe at long range and of specific model is preserved.
Cons....Its hard to see stuff. Hard to determine aspect and closure. In an MA type environment you can't tell who your friends are. Even when you know which planes are friends you can't tell who they are. No Icons is impossible outside of an historical axis vs allies setup and very difficult in one. Fun for only a few rather eccentric folks like myself.
The middle ground between the two would be ideal, especially if that middle ground magically preserved the Pros and eliminated the Cons.
