It sounds like Battle Royale mode by Ripple Effect will have more powerful aim assist compared to the Classic multiplayer modes made by DICE.
On the other hand, Ripple Effect has also worked internally on something called "Battlefield Triangle" where aim assist is interconnected in all scenarios possible for controller players: infantry versus infantry, infantry versus vehicles, and vehicles versus vehicles.
"They have their own set of unique parameters, settings and tunings when it comes to aim assist. So, we have a holistic controller experience, and the first feedback we received was, 'I don't feel the need to switch to another input anymore. I feel like the controller as a whole, with everything that Battlefield offers: vehicle gameplay, infantry gameplay, whether I'm fighting vehicles or I'm in a vehicle myself, I don't have to switch inputs. And that was a great thing to hear.
