Idea for Shadowfall

After most of the unlocks, the only big unlock is escaping as a legend. So playing as a legend is what most are after as of now. Leaving slimmer than expected lobbies. A lot of people see no point of playing the role as shadow(even though it's fun). With that said I had an idea come to mind. While running around hunting legends I though to myself, "how cool would this be to have a shadow skin for my legend!" Then another thought right afterwards, "maybe this could be worked in as a reward for X amount of legend kills as shadow with said legend." Either the skins can be independently unlocked with which ever legend one likes to play with. OR. The unlock could be across the board and unlock the skin for every legend. Either way. I would really love to have a shadow Wattson skin. 😉
