More and more cosmetics are added that I feel seriously affect gameplay. For example the heavy has body cosmetics that can make the team he's on virtually unnoticeable: especially if painted slate or one of the reddish/warm browns. If you look at the first cosmetics added to the game they don't stray far from the original characters so that class recognition wouldn't be confused. My greatest worry is bulky cosmetics that obscure the silhouette making class recognition more difficult. I like this cosmetic but I feel as though it would be hard to recognize the wearer as a spy at first glance or from a great distance.
