It's not that people don't like the game, it's that a lot of people are finding it unplayable.
For you there may be a small amount of lag but for others it's such an amount that it makes a huge difference between winning and losing a gunfight. How would you feel if you felt you lost in a situation that you usually win 9 out of 10 times? You then watch the killcam and it's completely different to what happened on you screen? It's impossible to do well!
The answer isn't returning the game. I want the game, I just want it to be evenly matched when I play!
I could forgive them if this was their first game but these issues weren't there for Blops 1. The saying is 'if it isn't broke then don't fix it', unfortunately they have done just that.
There are people who are not even able to play the game, should they take the most anticipated game of the year for the reason they can't get on the server? They shouldn't have to answer that question, it should be a case of whether they like the game or not.
They are also well aware of the problems and they will do what they can to fix it, otherwise they face a lot of negative press etc.
Oh, don't get me wrong, I understand that people are mad due to the quality they are getting, all I'm saying is that they need to flood the twitter and support pages. And as far as the problems of a new game, CoD has always had problems the first week or so of release. I've been playing since the first CoD and it's been like this from the beginning.
