What makes "low effort" weapons so popular in this game?

Hello there BFV subreddit, I have come here, with a slightly controversial / hot take post, but coming from a genuine thought.

So, as you know, Battlefield V has weapons... And, it also has a WEAPON Meta, obviously. And, the selection is quite large really, we've got SLRs, Semi-Autos, ARs, Pistol Carbines, Bolt Action Rifles, Shotguns, MMGs, AT Rifles, Bolt Action Carbines, SMGs, not to mention the grenades and numerous gadgets. The variety is REALLY large, despite the game's lifespan and content drop being cut short.

Despite all of that however, one thing that I (and maybe someone else too) have noticed, is how majority of weapons used by people are... Kind of, brainless? Which gets me to the title of the post, being "low effort" weapons.
Now, what is a "low effort" weapon? Overall, in my eyes, it's a weapon that requires little to no skill or well, effort, in order to be effective at getting kills. Wether that is having a large magazine which makes missing forgiving, very low recoil, combination of both, or high rate of fire making accuracy irrelevant and so on.

Examples of "low effort" weapons for each class would be:
- Assault - STG 44 / 1-5, M2 Carbine (Technically you could say ARs in general, but these 3 primarly)
- Medic - Drum Mag Thompson, Type 2A, Ext. Mag Suomi
- Support - Lewis Gun, Model 37
- Recon - Basically any SLR, but primarly ZH29 or Selb 1906
(Now, THESE are what I consider relatively low effort in my eyes, but if you have different opinion, then let me know)

Now, what you probably noticed, is the weapons I mentioned, just to happen to be part of the "Meta" or, at the very least, are considered to be the best or even overpowered (in case of Lewis and ZH29). And this made me think WHY is that... And the answer is simple. Why put the effort using other guns, when you can use the easier choices? No, seriously.

This has been the case in BF1 (Hellriegel, Fedorov, SMG 08/18) and any game before that, but the simple reason is, people just want to GET KILLS. They don't care how they get them. As long as it's not cheating, any gun is fair-game. And, if it's easy to use, forgiving and doesn't demand much, why not use it? There's a reason 90% of Assaults use Assault Rifles, or how most Recons that aren't "I sit at the edge of the map" kind, use ZH / Selb.

Let's compare STG 1-5 to Gewehr 43 for instance, both first AR and first Semi unlocked, with no specializations, for the sake of fairness, primarly, the damage and magazine size (other stats will be mentioned).

Gewehr 43 does 45-28 damage, with a fall-off of no longer having a 3-shot bodyshot kill at roughly 100 meters. With a magazine of 10 (10+1 with detachable mags), means that at MAXIMUM you can have 3 kills assuming no headshots, and at a minimum, 2 kills (Technically 3, if you do two 4-shot bodyshot kills, and one 1-headshot 2-bodyshot one). Firing rate being 300 RPM and vertical recoil (ONLY) being at 1.550.

STG 1-5 by comparison, does 25.1-15.0 damage which makes it go from 4-5 shot bodyshot at 30 meters, into a roughly 7-shot bodyshot. THis means, with a magazine of 30 shots (30+1 if you reload), you can have at MAXIMUM, by doing the math, 7 KILLS in a single mag, or 4 AT MINIMUM. This means that it has 2x larger potential maximum kill amount per mag, and 2x larger minimum size. All while having less vertical recoil (0.75), 670 RPM and a LOT more forgiving mag size.

Despite the fact that talk about Semi autos being meta, and being really good, I NEVER see them used, because, as this one example shows, a AR can at minimum do better, and at maximum, than a Semi auto, and this is only THIS Example. I NEVER see Semi Autos used, or Pistol Carbines, Bolt Action carbines, or such, and mostly the guns I mentioned are what's used, rarely something else!

So, why is it? Is it because of what I have been assuming, or is there something else to it? Do let me know!
