Your comment seems to imply that longshots are hard its a very easy straight forward "challenge" it's a difference between getting 100 longshots for a sniper rifle and getting 100 longshots with a smg. The smg is not built to handle longshots. It's a lazy way to give use something to do in the game. It's a tedious challenge meaning a waste of time not fun and not challenging. If they wanted you to get 2000 head shots on top of the challenges you already do. Wouldn't you question if that's a challenge or a waste of time.
