The "freeze" bug happens when you rapidly flip up after getting knocked down. Sometimes you immediately flip up and just stand there in a sort of "pose". It takes about 2-3 seconds before you gain control of your movements. It has nothing to do with pings or PC quality. It, like the "sliding around on your feet" when rolling bug, is random and chances are still there.
Although it would of been nice to see the Dark Side get a little boost to be more on par with the Light Side, on paper the patch sounds good.
