I think I recall that all the classes should be identifiable by just their silhouette, and with certain designs, that certainly makes sense for the feet as well.
I know I’ve killed people from long range through a small hole in plenty of games, including the foot. Damage is damage, depending on the game.
Yes, I was a useless sniper in my younger years. I’m not proud of that. I tend to enjoy support type roles more in my old(er) age.
