Not impressed by the patch, but hey it gives us the DLC too.
Things I like:
Firstly, Back to Karkand!
The patch fixes the IRNV over-powered issue. They can only really be used a short range, which I think is fair enough to prevent any further camping that IRNV might contribute to. They have moved the chat box, it's no longer in your face, but moved, one can now view previous messages by simply opening it.
Portable suns have been toned down, although will still melt your retina if too close. The tower on Caspian now collapses, that provides many with hours of entertainment in the long run, although the fact that it's based on a timed event is annoying. They have fixed the TV missile in the chopper, although it appears it's more deadly than ever (Saw someone camping with a chopper, firing TV missiles into the enemy base:/)
Other than that, HUD colours look better.
Things I dislike:
They screwed the choppers aiming, rockets don't appear to line up with the crosshairs. Stability is still a problem. increased the jet cannons damage to all targets. Only method of downloading the patch is via Origin, no manual download option.
Sure there are a few more that I forgot to mention, but the above jumps to mind.
