The Medals

What happened?

Why did so many of the awesome medals disappear?
Perfection is gone, wheelman sprees are gone, sniper sprees are gone, etc.

Also why were some good ones changed? Like the sniper medal which used to be for sniper headshots only, is now for any sniper kill. There is no difference between a sniper kill with bodyshots and a kill with any other gun in the game. The medal should be for if you can actually get a headshot with it.

Please 343, at least add some of the classics back that have always been there like perfection and fix some of the other classics like the sniper medal.
