The bugs are really not that bad anymore. The game doesn't freeze up too often anymore (even better if you download it on your system so you dont have to run a disc).

The bugs really do not impede on the game anymore. Sure sometimes when a building is collapsing and you are in a area that looks safe (like parachuting out of the building) it will still kill you.

The biggest issues still in the game that actually affect anything is-
The audio not loading for the first minute of a match, reloading sometimes failing to provide an animation, and iron sights sometimes glitching upon aiming down them.
