My stepson insisted on getting CoD:G when it came out - he's a fan of the CoD:BO series as well. It's a double-XP weekend right now.
He's not liking it as much as he thought it would. It doesn't help that he's got controller issues that keep him from using the game very successfully, but he also commented that he didn't like that the multiplayer maps have become much larger - he felt that too many players were using it as an excuse for camping. He doesn't consider that there are ways to counter such a strategy. In real-world fighting, an uncamouflaged sniper that camps in any small area for any length of time should be known by another name - "nearly-stationary target!" They move just enough to end up getting spotted, but not so much that they'd actually abandon their little patch of paradise. NSTs are only surpassed by cows for the title of "easiest thing to locate and kill." A wise sniper wouldn't hold a position for more than a couple of shots before melting away and popping up elsewhere precisely because they don't want to become campers/NSTs. Simply put, dealing with NSTs requires more tactical movement than simply charging through open areas and praying to move effectively without getting taken out by someone you can't even see because you were running too fast.
Among the first things I learned in aikido was to not get attached to anything - a weapon, a patch of ground, whatever. Staying in motion keeps you alive, while fighting from a single location makes you all too easy to find. If anything, you use your opponent's attachments to their disadvantage - someone focused on hanging on to a weapon or not straying from a specific area isn't adequately focused on dealing with immediate threats until it's too late. When they want your jo or the patch of land you're standing on, they're focused on that and expect you to give resistance - release it, give it to them, and when you do something so unexpected, they're unequipped to deal with you taking advantage and laying them flat, because you opted instead to focus on the real goal, stopping the opponent.
