I bought Battlefield because it didn't have SBMM and wasn't COD

Yes, BF6 is a fully manipulated game. Casual mode is the worst, it demonstrates how the algorythm changes, with enemy bots auto adjust to you fully, to the point they can kill you one shot headshot with DMR while running, or just RPG your tank from also within 10 meters. At the same time friendly bots dont do anything they just stand around you, waiting for you to do the job, not defending or killing, not shooting the enemy tanks at all. You can read more here in the forums. Good job if you uninstalled the game.
