I'm one of the people that take unrated a bit seriously when playing it but still try some things out. Unrated certainly isn't either risky or rewarding but I would I hate if they make it risky with ranks as some suggested cuz it ruins the whole point of it. Problem with it is everyone takes it to lightly and never tries to win. I suggest a long term rewards system that's victory dependant like gunbuddy, sprays, or skins parts that you collect 50+ of to get them granted you only get a part for every win. They can choose to make a cheap camo or spray and players can grind for it the whole month or week. One other idea I heard is encouraging stunts and risky plays in gamemode specific missions that grant colorful cool titles. I'd actually take a colorful title.
