For the non-English speaking, I'll try to clarify.

What happens when any game releases a patch? Not everything is the way everyone wants, no matter how much work or effort or balance is taken into consideration. So in effect there will always be someone who is not satisfied. And those who are not satisfied take the most opportune time to express that unsatisfaction (usually 2-72 Hours after the patch) to have anywhere from a snide remark to a full fledged diatribe about how they were either ignored, the developers don't know the game, didn't have time, etc.

This is true of all games, so it will inevitably happen again and again. Though to be fair I also expect some amount of praise and thanks given to IW for whatever issue/aspect/favorite sombrero they felt was addressed in some way and agree with it in some fashion.
