I didn't read through all of the comments since the patch, but I'm curious if anyone else is seeing more lag / bs since the patch? I've never had an unfair moment in the game before, everything I did on the screen counted. If I died it was always deserved.
But now it seems the opposite. Several times, among several servers, I've had tons of "bs" deaths, where I unload on a guy point blank, and get little or no hit markers, and all of their bullets seem to register 'instantly' as if they have a shotgun (even if it is not a shotgun) and I just die. If I use shotguns it amplifies the problem, because you know that an 870 at point blank range will kill in one hit, or at the very least, do ANY damage, yet several times I just watch my 870 fire, it animates, plays the gun fire sound, deducts a bullet, shows the spray, yet no hit marker at all I just die and the guy has 100%.
I would say maybe just a bad server or something, but it's been in every lobby since the patch. It makes it harder to get kills (not impossible), but more than anything it just makes the game frustrating to play because, and I hate to make the comparison, but it is exactly like COD now, where what you see on the screen does not always register.
I'm not sure what exactly they changed? For some people, who had issues before, it's probably better than ever, but I guess they took away from some of us to make that happen. FWIW I've heard some other guys have similar comments (and comments indicating it was improved). The end result is that the game is barely playable now (IMO). I switched to BF3 from COD, literally specifically to avoid this issue because it makes gaming too frustrating for me when what I do does not count/register/have any meaning/effect

It stinks that it has followed me now that the new patch has arrived.
Other than this issue, though, I think most of the other changes are welcome:
-Air support seems more balanced -- it is much more "fair" feeling in how and when you can or can't shoot them down. A coordinated group of people can take them down with relative ease, yet when I've been in the air, it hasn't been a huge problem of getting shot down a lot. Time will tell how this works out in the longer run, but as a fan of balance, something had to happen, especially with the jets.
-I do like all of the changes to the minimap, definite improvement visually to quickly see whats going on.
-I do not like how the patch monkeyed with all of my classes / weapons / attachments. I had a lot of them set up the way I liked, and frankly, I don't remember how a lot of them were even set up. Annoying that I need to use trial and error to see/remember how they were.
-A lot of the guns seem to have more recoil making them harder to use. This part sucks because the guns I'm used to using I can't really use well anymore (they seem to suck due to increased recoil effects), but I'm branching out as a result and finding some OK alternatives. Too early to judge this definitively one for me.
-The increased suppression effect is interesting, but not necessarily unwelcome. Need to play more with it, but it kind of feels like how it should have been from the beginning. Definitely a very noticeable effect now that you need to watch out for. If you get heavily suppressed, which happens regularly/easily, your gun just points way up and you cant bring it down to aim no matter how hard you try lol. Have to duck and cover. I've been running squad cover on all my classes as a result, but it doesn't help all that much (well if it does, even with it the suppression effect is still a nightmare).
-Definitely easier to kill tanks with tanks, and seemingly with ground rockets / javelins too. The tanks seemed a little harder to get kills with the main gun, but I haven't tried it all that much to be sure. Overall, I would definitely say the effectiveness of the tank has been reduced. I'm a tank whore, so it makes me sad, but after some of the runs I've gone on, where, with a good engineer, the tank is damn near invulnerable, I guess it's probably more fair now.
-The horn on the jeep just about makes up for everything. I love honking that thing, and unlike BC2 at least other players can hear it! What a blast. The little things...

-It's nice not having MAVs buzzing everywhere non stop and having to watch out for them. People have really knocked that BS off, which is certainly welcome.
-Bugs... I haven't yet noticed the audio bug, I have seen a few times the no animation reload bug, I have seen a couple times where I still hit someone 5 times with the paddles to revive (though I have noticed it is more reliable than the past -- the range at which you can do it does seem greater, but it's still not perfect).
Overall, the patch is great except for the bullets not registering problem, but unfortunately, that's a big problem for me.
