What I am concerned about is... If we just nerf the guns, the console players will still have snapping to targets and 1.5x better recoil. Majority of MKB players are casuals same for consoles, so if casual vs casual goes against eachother the controller would most likely win in this situation based on the aim assist and better recoil. There is no casual that reacts to someone shooting from behind before its too late anyway. The easy movement with mouse doesnt benefits casual players as snapping to target and lower recoil does with controller.
If you look at BO6 for example. Extreme majority of player played with controller, also former MKB players like myself changed input device. You dont have to put the same effort as MKB player does to achieve the same level of aim as a console player/controller even in the pro scene. You're much more relaxed and can play for longer hours than with MKB, because you dont need to throw your arms around like a maniac, you dont need to memorize the movement of enemy player (strafing) etc. Especially with games like cod that are fast paced and domination/king of the hill mode in BF6. I had a headache after 3 games in bo6, when I swapped to controller I played 10+ games before I needed to take a break.
Now I am refering to a different type of game and I dont have facts about majority of player playing with controller on pc except that everygame I played they had the controller icon, even on pc. Which indicates that they use controller on pc or a console which have 2 different icons. When I achieved highest diamond rank to advance into crimson, there was only players on controller both pc and console.
Now after all my crappy talk. Sorry about the length, but the only way to actually do something with MKB is to do the same thing they did on halo infinite. Which gave MKB aim assist aswell. That is not the way to play FPS games in my humble opinion and probably most people (speculation). Also should we go for AI assistance in FPS games? Should we remove all form of skill in competetive games? It should be fair for both sides, right now console players have it extremely easy because of the low recoil weapons and nerfing all weapons will hurt MKB the most. It is already hard to control the aim with the bloom added feature while moving, I am a strafe shooter so that is a pain with a weapon with 30 precision (with attachments aswell). I have to stand completely still to have the same accuarcy as the person with a controller do that can walk and shoot. Because of the low recoil they can modify the weapon with different attachment that benefits both vertical/horizontal or bloom etc.
Edit: Also, BF6 is an objective focused game. Only time you actually run and have to check your back is from point a to point b. Then you sit there with healing bags, grenade dispenser, shields, mines, claymore etc. I do agree that PC have better keybinds modification than controllers, but they also can buy an elite series controller or ps5 dualsense edge with extra buttons.
