I disagree. Playing this one map is a lot smoother, yes. But, in no way, is it related to BC2 from my point of view. Yes, it has bugs and glitches. But, it is still in the alpha stage. The gameplay is a lot different from BC2 which I lag all the time in. This game, I do not lag and everything is much more clear. In BF3, I can actually see my targets, where in BC2, I had to guess where they were.
There is only one thing I think DICE should fix and that is when I right-click my mouse to aim, I shouldn't have to hold down the button to do it. I should be able to click it to bring up the scope or sights to aim, then click again to lower the scope and fire from the hip.
