@Padding_Ur_Stats If we speak strictly from meta gaming PoV. In a duel between two skilled FPS players, the one who can take even slightly more shots have the advantage.
Also the significance of the extra bullets to kill is inversely proportional with the rate of fire of the weapon. A fast firing weapon will see the least difference. A slow firing weapon will be dramatically weaker.
I do not know how active you might had been during the BFV times but we had a certain crisis at the time.
After BFV released in November 2018, DICE did a patch during Christmas 2018 that made almost all the weapons need 1 more bullet to kill. People hated that because it messed up the gun balance and muscle memory.
DICE did a patch that mostly reverted those changes soon after.
Then on around Christmas 2019 for some reason they did almost the same patch again and people were furious again (ruining the goodwill they generated with the Pacific maps) and they semi reverted it again.
Angel's armor distribution is in a way a similar but temporary Bullets -To-Kill patch that is unpredictable and inconsistent since some soldiers (those with no armor) need fewer bullets while others (with armor) need more.
I hope that helped explain this whole afair a bit. 🙂
