The April 3rd update appeared to have corrected the massive freezing I was experiencing - appeared from the last update. In the limited time I played last night, I did not experience anything out of the usual online type stuff. Hoping that it wasn't a fluke and that the freezing every 2-3 seconds has been fixed for me. Didn't see the standard framerate drop either in that time period.
I have the DLC maps, and now that they are in standard rotation, may have altered the playing field a bit as I believe I am only being matched with other DLC players... Who knows.
