While the overwhelming majority of players HATE the "no icon" settings, I personally love them. It adds so much more to the experience NOT knowing what plane type, or HOW much E they have, and it is FAR easier to bounce and be bounced!
It took some adjusting at first, but I eventually got used to, and learned to love an iconless environment, and flew in it pretty much exclusively. Even a limited icon environment (D300) is more fun for me.
Unlike the main arena's, it is pretty easy to ID AC in a fixed planeset without the neon. The shape and colors start to imprint themselves and you can tell many AC apart from a surprising distance, even with ye olde 17 inch monitor.
Sadly, the demand for such an environment is too low for it ever to be implemented imo. The AvA has a small audience as is, and reducing the "gameyness" further would create shrinkage, and reduce the likelyhood of hooking new flyers to the over all concept.
A good compromise would be removal of the distance marker, and replace it with plane type, or just simply "enemy".
I have yet to do it, but I would like to try running some missions using NO icons, and NO onboard maps. AH has enough land marks that it is feasible to use printed maps for navigational purposes to complete a mission, rather than a GPS. That would be pretty tricky for both buffs and escorts, especially when the fighting starts.
Alas, we have what we have...
