Something i'd love with "Legendary" cosmetics
It was said in the 4th anniversary stream that Legendary cosmetics will completely change the character you are playing to someone else. I find this to be a brilliant idea and something I would love to see is Legendary cosmetics for Bill. So that way he can be changed into other Left 4 Dead characters. I get that we already have outfits based on some of them but the proper characters would be freaking sweet!
