Anyone else think that Modern Warfare 2 online air support is overpowered?

I been p[laying for a couple days now and I'm pretty decent with ground combat, I usually crouch everywhere, camp, and ambush hardly using ault riffles, instead my sniper or light machine gun (mostly sniper) But anyways, after getting my first kill-streak reward (care package) I get something like a predator missile and always kill at least one enemy, which rewards me with another air-strike which wipes out another couple rewarding me with the chopper. This ends up wiping out 5-10 people and if I get a chopper gunner or AC130, forget it... My K/d will end up being like 35-6 or something. It's awesome and all but it seems a bit unfair seeing how after that blow to the enemies they end up losing which is kinda not right since everyone on my team is negative K/D and their team they're all positive. Any opinions?
