Glad to have you back, and thanks for this very honest and straightforward response! I hope your time with your newborn was fun, it's wonderful you got time off for that! :)
I don't really expect a response here, since you're already being flooded with replies, but since the team is looking to address some of the QoL/etc issues the community has had for the past few months, I've got a couple to consider passing on to the team that aren't the usual "authentic uniforms / vehicle cosmetics / unreleased stuff in the files" that we tend to see around here.
Back in BF4, even before CTE started, I was regularly on comms with one of the LA animators (Ryan / AnimationMerc), and through BF4 and BF1 we got pages and pages of fixes, changes, and improvements done to weapon animation, function, and even name correction done through BF4 and BF1, especially BF4; he gifted me the DICE Friend dogtag in BF1 too. :D However, he moved on from DICE a few months back, and passing on some of this stuff has been extremely difficult since then, partly because I don't know who on the team actually handles / is passionate about this sort of stuff.
While technical function/gameplay errors are drastically lower in BFV (as well as BF1 at launch) thanks to members of the team constantly upping their standards, there are always things that slip though (incorrect damage models, magazine capacities, etc).
However, BFV's largest weapon authenticity type issue is naming schemes/standards. Or lack thereof. But the issue here is that because names are just a UI thing (zero gameplay relevance), because names have to go through Legal to be changed (which is doable, we got names changed in BF4), and because it's not something I think any devs active on reddit/twitter/etc actually handle themselves... I've had about zero luck even finding a dev that might handle this, let alone actually being able to talk with them.
Battlefield, since at least BF3, has been stellar about authentic and correct names for weapons and vehicles, but BFV has been... a total mixed bag. In BF3 we had, for example, the F/A-18E Super Hornet and Su-35BM Flanker-E, which are stellar examples of Battlefield's high-quality/authentic naming standards.
Meanwhile, in BFV, we have things like Lee-Enfield No.4 Mk I, Ag m/42, and Panzerbüchse 39 (stellar), to VGO and M1911 (too basic, ditching the variant designations like the Lee-Enfield includes), to Boys AT Rifle and Kar98k (colloquialized names), to Trench Carbine (entirely descriptive, no actual name) all in the same weapon pool.
On top of that, we also have errors clearly made by grabbing one of the first Google results, a couple that are simply incorrect entirely, and a general lack of consistency among weapons of the same nation/military, like MP40, FG-42, and MG 42 all in the same game (letter-letter-space-number-number is the correct German style).
In addition to all that, the vehicle devs seem to still be on the "NAME EVERYTHING IN ALL-CAPS" train that we finally got away from in BF1. Being all-caps was BF3/4's biggest name issue, as plenty of names and designations depend on a mix of upper/lowercase letters to actually be correct; BFV has the StG 44 (perfect) sitting alongside the FLAK38 and PAK40 (instead of FlaK 38 and PaK 40). This also makes the short-form/acronym and roman numeral elements harder to identify and more confusing for casual / less knowledgeable players, for example SPITFIRE MK VA instead of Spitfire Mk Va.
Vehicles also entirely omit the accents and special characters that the weapon names in BFV do use, which leaves us with things like Panzerbüchse 39 and STURMGESCHUTZ IV (instead of Sturmgeschütz IV, with the umlaut) in the same game. We also have omission of key elements of names, such as PANZER 38T instead of Panzer 38(t), with the brackets and lowercase, and so on.
Given we're about to get a bunch of Japanese weapons and vehicles, which are probably the most "complex" to get correct/consistent, my experience tells me those might end up being a bit messy too.
I don't believe it's that any of the devs "don't care" or "are lazy" or anything like that, but there definitely seems to be a lack of standards set for naming in BFV, like maybe all the different devs that work on these things are individually naming their own work, which gives wildly inconsistent results. I have a Google doc running with a whole list of corrections for this stuff, but it's never gotten any traction, with all the devs that actually post around here being in other departments and such.
I realize this is pure QoL and ultimately not overly "important", but I do feel it's this sort of detail that's made Battlefield great over the past decade, and it's also definitely something the vocal parts of the community wanting "authentic uniforms" and such would appreciate.
Sorry to bother you with this, but if you actually read the whole thing, thanks. :)
