I'll actually push back on "weapon variety" as someone fairly critical of what we've seen so far.
I'd rather have 5 well-constructed/meaningfully different assault rifles than 15 for the sake of unlocks and progression. BF was better when it wasn't chasing CoD engagement loops. 90% of weapons in BFV within any given category are just variations of one another with slightly different ROF and range dropoffs.
I agree, it ends with everyone screaming for their favorite gun to get buffed or the best one to get nerfed for a while and a lot of time gets wasted on mostly bad balance changes and reverses. Worst case they force weapons into weird niche roles that don't suit what you'd expect from the gun at all. Worse in contemporary/near future settings as well I think because most guns should be very powerful and very fully-automatic so the forced diversity feels even more arbitrary, near future gets some points for having a chance to be more experimental and not just have a bunch of bullet hoses... but that's probably what it will be.
I think 5 assault rifles is too many really... burst, semi-auto, low RoF low recoil, high RoF high recoil, middle ground would make the choice too easy aaaaand we're down to 1... 2... 3... 4! SMGs can have one very high RoF variant and I hesitate to say Suomi-high because in online settings it yields boring 1-on-1s, when everyone can pick every gun you don't need a slower/more accurate model, you pick assault instead. Sniper you need one long range and one close range. You don't need shotguns because they cannot be balanced to play well, you hate playing against them or you hate using them. You don't need HMGs unless you have suppression. You need to have 24 handguns and one revolver with one hit headshots because every one will use that anyway. And boom! There's your 32-but-really-8 gun BF that fans will hate and scream at for all eternity! If needed throw in a 400 round HMG that'll lose out to every other gun 99% of the time.
I mostly didn't like the customization in V either, for one they gave experienced players straight up upgrades (that were admittedly easy to obtain), and furthermore most weapons had a clear superior upgrade path with a few exceptions... and a lot of upgrades were so close to meaningless that they just felt like needless padding, like the quick scope upgrade giving like a 72ms advantage... scope customization and the 3x scope ended up being terrible for balancing HMGs and Assault Rifles against snipers... so drop customization as well! Haha! There's your 8 gun BF with no customization, the most popular Portal mode!
