I love that these guns are becoming available, but I dislike the RNG to get the mission. I would much rather have the mission drop more commonly, but have a harder mission to get it. Instead of making us do Night Falls to get the mission, why not give us the mission and do something like, "Do a Night Fall on X unique maps", so we might have to do 3-5 weeks of night falls to get all the required maps. Then we feel like we are working toward something instead of working toward the chance at something.
