I agree mostly with what everyone is saying.
Yes the taclight needed a small nerf, which I think they did.
The IRNV, I also had for some time but only started using it just before the patch. It was silly overpowered, you could spot guys you would NEVER see otherwise. However, the nerf they did to it completely broke it. Instead of aiding in seeing the enemy it now in fact makes it more difficult to see anyone, which to me makes it useless as instead of enhancing the guns it actually makes them worse.
The chat log is WAY better, color coded names and the ability to view the chat log at any time. Still not scrollable though (unless I am mistaken).
In conclusion though, the patch DID break the game. My game now crashes significantly more often than it did before. So not only did they not do any fixes for the crashes I was previously having, they made it worse.
I love the fact that they are changing and tweaking, but being a little too overzealous with some of the changes sucks, and from what I understand, the crashes are widespread, and I really think that fixing those should be the number 1 priority.
