Battlefield movement is already in the game.
I stepped back into the campaign recently to get the cosmetics, and man was I amazed at how differently the game played. The movement actually felt like a battlefield game, and not a BF skin slapped on top of a CoD game.
What really stuck out to me is what I'll call the acceleration of everything. As in, when I started to sprint, it actually took my character a second to get to full speed. When I try to strafe left and right, it actually takes my character time to stop going one direction, and then start going in the other direction. Even sliding didn't feel as CoD-esque.
I doubt EA/Dice care, but this should really be the regular movement in multiplayer. You watch a bunch of the BF content creators, and all the old, genuine creators that were making content for BF all the way back in BF3 days, they play BF6 like a real BF game and have legitimate complaints about the direction the game has taken. Then you have the CoD creators who just happen to be playing BF because CoD has turned into such a trash game even they won't touch it. You can ID these players by the fact they are ALWAYS support, only give ammo to themselves running the goliath pack, and never run any of the other support gadgets and rarely ever revive. Whatever these players say the game needs, do the opposite, or BF will die a slow death just like CoD has done.
80% of your revenue stream on PC has left the game. They left because they came in expecting to get Battlefield, and got Call of Battlefield instead. It isn't too late to course correct. There are no real competitors to the battlefield experience. There are one hundred million competitors to the CoD experience. There are that many and more competitors in the battle royal market.
Make Battlefield Battlefield again.
