I wouldn't exactly say Killstreaks are overpowered, Care Packages are usually just ammo drops, and practically all the other ones are a lot less effective when people are using Cold Blooded, not to mention that most of the killstreaks can easily be shot down by one or two stinger missiles. I usually play with a class with Cold Blooded and a Stinger as a secondary, and I usually take down harriers and helicopters before they can kill anyone.
Campers however, can be a bitch. And something I'm starting to hate by now is the amount of people running around using nothing but G18s. They have terrible accuracy and recoil when you're using just one of them, but as soon as you get Akimbo, it seems as if the cross hairs are 3 times smaller, and recoil is almost non-existent.
EDIT: One other somewhat annoying thing at times, are noob tubers. Not as annoying as the Akimbo G18 people, but it can be annoying when someone ends your streak with a randomly shot grenade. Worst part is, if you're going for the Mastery titles, you need at least 20 kills with the grenade launcher, which basically forces anyone trying to quickly get 20 kills with it to just noob tube for two or three matches.
