I mostly play an assault, what I'd love to be able to do is switch the side that the camera is over and the hands I'm holding the gun with. Right now with my AR being in my right hand I have an advantage in counter clockwise advancement and a disadvantage in clockwise ones. This is especially true when I aim down the sites. Just a suggestion, not a big deal either. If any of you ever played Metal gear solid 4, you know what I'm talking about, you'd push in the right trigger and it would change the overhead from left orientation to right, and switch hand locations.
This advantage has been noted by the developers, and is why the maps are designed rotationally symetric.
furthermore, devs said that, in order to make hands switchable for all weapons of all classes, it would take twice the memory and processing power that it currently takes to make weapons operate. thats a lot of the game being doubled right there. if it was just a matter of copy, flip horizontally, and paste, id say fine. but apparently there are more complications to worry about than accidentally flipping vertically instead.
Thanks for letting me know this has already been noted I did do a quick search for it but didn't see anything, I guess It's calls a wishlist for a reason =P.
