So I just started up a game to have some fun rounds and found myself in one of my favorite 16-player servers, the map was a conquest in the snow village(of which I can't remember the name from), no lag, everyone generally has <100ping on it, so that's all good. 
Except out of the 8 enemies, 4 were medics with the M60, 2 were using a M16a2 but mainly shooting 40mm grenades with the extra explosive damage and another assault which was using a M416. The other player was a sniper with a Gol. 
 
Now I can tell you that while we put up a good fight, it's simply not fun to not being able to kill the enemies in a realistic fashion, if you meet one of those medics; no matter what you pull; you're dead and the best I could do was to drag them with me.  
Of course there's still moments where you can kill them while they're running and they've not spotted you.  
 
But the obscene amounts of times I died from a random explosion, or a close encounter I knew I couldn't win made me want to stop playing, at least for today. 
 
In short then: 
I really hope that DICE can somehow balance these weapons better in an upcoming patch or I can see people just getting ticked off by these kinds of matches.

I haven't noticed any issues with the 40mm grenades. I'll grant you the M60s are powerful, but nowhere near as stupid and balance-breaking as the '87s in MW2. Could they use a patch? Maybe. But, I don't think they're too bad.

hysterics.

IMHO, based on what you're saying, it's not that the weapons are not balanced, you just had to face a really good team.  In your description, it's not just a whole squad that is organized, it's a whole team knowing their own roles and ranges on how they can dominate their opponent.  It's actually a good example of how teamwork is important in the game and how efficient a win becomes when one team is more organized than the other.

It's not the actual teamwork, they were not really sticking together other than the odd 2-man team possibly from just spawning on a squadmate. 
 
Facing a good team is certainly fun, but these didn't seem like superb players, most kills were simply them running up to me and holding the shoot button. Rarely did I see one crouch behind a wall/car and shoot me from there, for instance. 
Don't get me wrong; I don't have a problem at all with getting my ass kicked by a well coordinated team, or even a team of average players. They deserve to. But seeing people just run up to you guns blazing and killing you nearly every time while you're crouching and/or scoped for accuracy is taking the piss. It's not a one-time thing either, it's something I encounter often.

I get your point, it does get frustrating sometimes.  I had a game once when I got killed around 10 times consecutively by the same player over and over again.  Even if he seemed like the player who isn't strategic, but he does have a fast itchy trigger finger.  I guess it was just pure bad luck.  I just turned the game off and rested for a day or two, then came back again haha! 
 
If your team got owned big time in that match even if the other team wasn't really that organized, then I guess it's just bad luck hehe!  But it does happen.  Actually, I haven't really experienced dying from random explosions as bad as yours, maybe they're just really good with the 40mm grenades?  Or they just really know the spots or choke points where players usually pass through or hide hehe! 
 
Keep on playing, there are really bad days to play the game.  When that happens to me, I just play a different game online game like Street Fighter 4 then I get frustrated more and get into a rage, then I simply realize, I love BFBC2 again! LOL!

The M60 is a powerful weapon, but I wouldnt go that far and the 40MM I rarely ever get killed by. The M60 could use a damage tone down, but its rate of fire is slow which is also a factor. The other LMG's such as XM8 I have no probelm getting kills with.

I think what they really need to do in regards to the 40mm and the Gustav is to give them some crazy self-damage. I think that would hopefully stop people from running around with their explosive weapon out and blasting people when they come around a corner. I can't even count the number of times I've been running up on a guy to knife him, and he grenade launchers me to death from a couple feet away, then walks off unscratched.

Yes the m60 is waaaay overpowered, and I believe we can expect a fix.
 
The 40mm and gustav are in need of something to help prevent abuse (I like this dude's idea of super high self damage ^^) but are not nearly as much of a problem as m60s. 
 
GOL snipers are way overused in hardcore mode due to the accuracy. But I don't expect a fix for that.
 
What BF3 needs is leg crippling to prevent the ridiculous number of one-shot leg kills with varying weapons in varying modes. Like Last/Final stand in MW2 except standard for everybody and only happens when the legs are mutilated (ie not triggered by headshots and stuff).

"Actually, I haven't really experienced dying from random explosions as bad as yours, maybe they're just really good with the 40mm grenades?  Or they just really know the spots or choke points where players usually pass through or hide hehe! "

More broken than anything is the medic revive skill; theoretically a team full of M60 medics with defibs is unstoppable. You couldn't wipe them out unless they were all standing in a mortar strike. When you revive someone they should be at half health and have no invulnerability.  
 
Personally I think the 40mm grenade is fine. It doesn't work in close range (simply doesn't detonate for some reason), too inaccurate for long range. Medium range is where it excels but only if there's no obstacles in the way; will also not work if you're against more than 1 person at once. 

40MM grenades aren't too bad. They have a much smaller blast radius than in mw2, so they're only really useful at medium ranges.
 
M60 is OP, that's a given. Freakin beam cannon of death with super accuracy.
 
Also, the Carl Gustav is still wayyy too powerful. I fire random shots off into the distance and get kills with it. Think the RPG from MW2, except with a scope and fires faster.

Just curious; what platform do you play on? There are a lot of good 40mm users on the PC at least. "

As mentioned, it just sounds like you came up against some decent players.

M60 could use balancing, but the 40ml gl's are fine, as there is a bit of a trade-off when you use them.

" I love the M-60 "

Haha... now it's gonna turn into yet another thread where big_jon tells us how good he is.
