We need some kind of icons at ranges where in RL you would be able to make an ID, but where present video technology dont give us the same possibillity.
At short ranges the video makes it possible, but not at longer ranges, and it will vary depending on how good equipment the players has.
To even out the difference in player equipment, and the technology limitations, some sort of icons are neccessary.
It will still be possible to sneak in on planes, as is often done now. The main thing that reveals sneaking today is the in-flight dot-dar on your clipboard. Not the icons.
In AH I have gotten the habitt of checking clipboard more than I check my 6, and I dont like it. Its far from reality. That particular part where better in WB than in AH.
In WB thay had two arenas. The combat arena had the dot-dar, while the WW2 arena had not. Thus there where an arena for both the quake players and those who wanted more reality and an historic environment.
We have both types of players in AH, and I can not see that all can be happy with a common solution in MA.
On that part WB had developed during many years longer than AH. That is an experience I think AH should adapt as soon as possible.
