The range of most weapons are terribly balanced

To add, LMGs should be balanced to mainly be used as stationary weapons. Like BF3 had it. Also best to be used at medium to long range.

I think the SMGs are nothing special in this game, they are often not very usable due to map-design.

ARs and LMGs are probably too strong at range, but again (as others have stated) the maps are pretty big in general.

And ARs have always been 'the best' weapons in BF (perhaps DMRs in BFV were pretty good though).

LMGs being more stationary was tried in BFV and that wasn't a success...

Dropping the suppression from LMGs or MGs in such a Game is a pretty dumb decision. Depending on the current batch LMGs are better than ARs. I don’t know why the decision to drop suppression was taken - I assume for “…better player experience…”. If you don’t have suppression get rid of LMGs as weapons category.

Seriously, I shouldn't be getting sniped by LMGs from 300 meters away. The balance is so bad right now, that a lot of the weapons are really good at long range.

Here's how it used to work in older games:

SMG - Best for close range, good at mid, and bad at long range
LMG - Good at close and mid range, bad at long range
AR - Best for mid range, good at close, and bad at long range
Marksman/Sniper - Best for long range, good at mid, and bad at close range
Utility - Very good at close range, bad at mid and long range
Handgun - Basically last resort when you're out of bullets, that's why they're a secondary

Now here's how it is in 2042:

SMG - Best at close, good at mid and long range
LMG - Good at close, mid and long range
AR - Good at close, best at mid, and good at long range
Marksman/Sniper - Best for long, good at mid and bad at close range
Utility - Bad at close, bad at mid and bad at long range (not including rorsch and crossbow, they shouldn't be in this category in the first place)
Handgun - Most of them are fine, but the biggest offenders are the G57 and PF51. Those two are basically SMG's with the right attachments

It's pretty clear how unbalanced these weapons are. The gameplay has become so annoying due to this. It also leads to many people camping with automatic weapons instead of having a normal gunfight. And given the nature of how open the maps are, you end up being shot by these campers. In older games they were snipers, so you could actually dodge them, but now they just rain bullets giving you no time to escape.

Here's my experience with these weapons. 

SMG - RM68 beats most SMGs close range- even if you hit first and get headshots, since the headshot multiplier for this category is extremely low for reasons unknown, to the point where even the g57 beats most of the SMGs in TTK. 
LMG - Some of the LMGs are very powerful, but still get outperformed by ARs since these often get extended magazines anyway and with the fast TTK it doesn't really matter to have a big magazine in 1v1s. 
AR - RM68 being the best with Scar being close second. 
Marksman/Sniper - Rm68 is better at every marksman rifle at any range. Snipers they can still compete with due to the slow bolting speed combined with spread multiplier after either moving or shooting your first shot. I.e. if you wiff you are dead. NTW might be the only sniper that can compete with RM68 at medium range since if you hit there is nothing they can do. 

Utility - Overall bad and gimmicky weapon category where 99% of the weapons aren't competitive. Hilariously the super 500 outperformes even main weapon shotguns. 

Handgun - G57 and PF51 as you say are just SMGs that are sometimes better than a lot of the regular SMGs. I don't know how the glock gets higher headshot multiplier than regular SMGs when they have same caliber -.- in fact some smgs should have higher caliber. 

There is only one of two weapons to reasonably pick currently and you guessed it, it's the RM68. Scar can compete. Only competitive sidearm is g57 and the super 500. 

One would think that with the server-side "speed changes" that DICE allegedly should be able to do that it wouldn't take an entire season to tune down two * weapons, but alas that's not how DICE works I guess.
