There clearly was no real testing. IW failed massively in the testing department before they released the game, thus why we have these patches. The more I play the game the more poorly thought out things I see, like the infinite care package glitch, the elevators, the getting into the floor or walls of the map, stupid fixes like lets nerf a single 1887 but fail to change the math on the Akimbo with FMJ. Or that the Attack Helicopter is completely worthless compared to the Harrier - "Hey, lets have two kill streaks that are the same number, but one can shoot down air support, has an air strike, and actually hits things with its guns, and can apparently dodge Stingers at random. The other one, well, lets have it just kind of fly around and do nothing." Srsly, I've had a Harrier take down a Pave Low and Chopper Gunner.
It feels rushed. Lots of little things completely over looked. Like match making. Can I have an option to search locally, so to prevent me from getting put into games where everyone is speaking Spanish? The ranking boards are still fubar'd as well, etc etc.
