The weapon balancing is a SECONDARY part of the patch, the PRIMARY effort of this patch is extensive bug-fixing.
What I got from Jason's post was that it was primarily optimization and engine fixes. They worked hard with the software folks on freezes, crashed, etc... I also gather they worked on some bugs, but mostly on improving the game's stability. Now since I reckon a lot of bugs that people have had might have a lot to do with the instability and crashes currupting saves, this will also help with a bunch of the bugs from that aspect. I don't know how much time they spent chasing down scription errors, like bad scripts in quests, etc... The game should be much less buggy, but more from a stability standpoint, rather than a scripting standpoint.
So what’s in that patch? First and foremost, optimizations and stability improvements. While there are bug fixes, our core focus was on improving stability and performance. We worked directly with first party platform owners to identify issues, and we have fixed a great deal of the crashes and lockups that people were experiencing. In addition, we scoured the forums and this patch includes weapon balance tweaks and other requested fixes.
I might have misread, but that's what I got.
