Ty_Ger07 Sorry but Cant be botherd typing a reply so here's AI's version.
Launch patch notes (1.0.1.0, Oct 9) mention ZERO aim-assist changes—no nerfs, no beta dominance data. Full notes:https://www.ea.com/games/battlefield/battlefield-6/news/battlefield-6-update-notes-1-0-1-0
ONLY AA talk is in 1.1.2.0 notes (Nov 17, live Nov 18): https://www.ea.com/games/battlefield/battlefield-6/news/battlefield-6-game-update-1-1-2-0
Verbatim dev text: "As we got closer to launch, we revisited aim assist tuning based on internal testing and the full range of maps and combat distances coming with release. Our goal was to make aim assist feel more effective beyond mid-range fights which was one of our focuses within Battlefield Labs and Open Beta. At launch, we increased slowdown at longer ranges, but once the game went live, we saw that this made high-zoom aiming feel less smooth and harder to control. After reviewing player feedback and gameplay data, we’re reverting aim assist back to the values some of you experienced during Open Beta and Battlefield Labs."
in summary: Beta aim assist was weaker than launch (specifically less long-range slowdown) and the Nov 18 Update 1.1.2.0 fully reverted it back to the weaker Beta tuning.
