Yeah that's what I was getting at, but didn't full explain my thought. Class balance is very balanced as of now, and I think nerfs will only unbalance things (so many times a nerf causes unintended results).
For something to require a nerf, I think it has to meet the "is this overpowered?" question, and be answered yes. For something to be overpowered, would mean that there is nothing in the game that can reasonably counter it (not including that same class or weapon). I don't think anything is overpowered in the game.
So the class balance team is just looking for things to balance, even though there's not necessarily a need for more balance? I think by trying to over-balance, you end up causing more imbalances than you had to begin with.
Also, just because people yell the loudest, doesn't make them right. I hate how it seems like whatever the hot button topic is on the forums gets addressed by the devs, rather than whatever the most logical issue is being addressed. And 20 people bitching on the forums, doesn't mean that the other 2000 in game would agree with their points. A majority on the forums, doesn't mean a majority in game.
