your comparison between GTA:Online and Battlefield is about as Apples/Oranges as it gets. In GTA:O, yea you're not going to stand a chance when it's your pistol vs their tank. it is damn near literally impossible to do anything about it (someone could probably figure something out that wouldn't work 99% of the time, but hey.)
Asking to nerf guns because they're too good? Unless the balance is really that far out of whack, it's usually uncalled for. You can kill someone with a "sub par" gun just as easily as they can kill you with their "top tier" weapon. You may lose in a static environment, but since when was live gameplay static? Shoot em in the back if that's what it takes.
There's a difference between poor weapons balancing and a power ladder that you're at the bottom of. Apples, oranges.
