COD is losing ground to Battlefield?  Lol, really?  I bought that game and couldn't stand to play it after two days. 

I bought Battlefield on the launch date without a preorder and walked right into the store, bought my copy and left one minute later.

When I bought MW3 I preordered and went to pick it up after work on launch date.  I waited in line for over an hour just to pick up my copy.  Yeah, seems like they're really losing ground.....

I almost always play TDM and KDR is the biggest measure of how good a player is in my opinion.  However, you can't simply look at KDR to make your judgement.  I just bought Black Ops 2 but haven't played it yet but in MW3 my KDR is 1.78.  However, all I do is run around the entire time looking for people.  I'm just as likely to go 20-18 as I am to go 35-5. 

As soon as I enter the lobby, I check everyone's KDR.  I make a mental note of anyone over 2.0 and pay careful attention to how they play.  If they run around and win gunfights, they're pretty damn good and deserve the COD respect.  If they sit in a corner all match, their KDR is fake and it's not a true measure of their ability.

The other thing I notice is the fake KDR guys who camp all match will leave in the middle of the round as soon as your start owning them...further proving they're fake.
