It is reported that DICE has reworked the movement system in Battlefield 6. The changes are not drastic, and players can still move fairly quickly around the maps, jump and roll on their knees, but various restrictions such as aiming speed and recoil will not allow you to abuse the system by making unthinkable jumps and rolls.
The changes were made taking into account the feedback from the participants of the Battlefield Labs program, helping the developers to make exactly the Battlefield that the fans want to see.
