This may just be an old player talking through the stained glass of years of playing, but do we really need to know distance?
I do.
Won't people get a feel for plane silouettes and subsequent bullet drop attitudes (in a pretty short time) anyways?
I am a lousy shot, and a lousy judge of distance, and I need all the help I can get.
Of course, if I had a better video card and monitor, it might help me in that regard.
On a different note, however, I do remember when I first started playing, the distances were absolutely essential.
Remember, you can always turn your icons off.
Oh, oh. I just thought of something...
How about if HTC added another option for icons, that does what you suggest? Then the folks like me who need to see the distance, have it. And you can your friend or foe only icons, without the distance.
