Don't you think this, and other issues, will be addressed at some point down the road? AH2 wasn't always the program we all came to love; it had its problems on rollout, too.
While I agree that there will be problems, the sound in a game that depends on location BY sound it is a rather important thing to take care of.
I just got a new headset because my old turtlebeach set finally started giving up (5 years of service) and the sounds with this new headset and sound system in the game is awesome, however the directional sound was far better in AH2. Challenge was working on a custom sound pack and it seemed like he found that the new system is more complex and far more versatile than the old system. He also seem to have some problems with how the sounds worked in the game.
It looks like there is still a lot of work to be done. Unfortunately, new players aren't going to be ok with such a sound system as it is.
