Yes definitely. There should definitely be some sort of light machine gun added as the 150k pk reward. It just makes Sense. As for sparrers, I think the m4a3 needs some more skins. The vector has 12 skins, and the m4a3 has 2, including it's original skin. It seems a little odd that a gun that requires 22,500 spar wins, has 2 skins.
