I disagree about quickscoping being skillful; you just need to put a tiny blob of something that won't harm your screen where your crosshairs would normally meet and it's literally the easiest thing in the world.
Back to the game: so is this new IWNET 'better' that MW2's? Have you players had lots of the usual migration/host/connections problems etc?
Seems to be identical. The lobby can still be painfully slow, sitting at 'waiting...' for ages. Loading a map, I am often waiting 1-2 minutes before getting into a match, or being dropped back to the lobby (you still can't quit during this time). It works 'adequately' but the issues from MW2 still persist.
