No, because you earned those.
I don't know what to do with the 10 that I have now. LOL!
I'll tell you this though, and I'm not kidding, I would pay $5.99 just for the ability to have different Scorestreak classes for different map and game modes. But I ultimately do recognize that this would be unfairly selling advantage to players. I wish they'd just just show a little good will toward us stooge customers and add that Scorestreak ability in one of the updates.
Gotta pick the load out you wanna bring with. I made my sets based on gamemodes I play.
