I kind of want prone, just so that I can laugh at how much easier it is to shoot a horizontal body from above when I'm jumping around as a Light Assault
But I really don't give a shit as long as the game mechanics don't make it mandatory or overpowered. Same as with iron sights. Just another way to play the game, as long as the developers don't make it the
only way to play the game.
But I'd be just as happy if they kept it out. I don't particularly want to see it and I think it would be a waste of development and balancing time. Just not important enough to the massive scale battles of a Planetside experience IMO.
