Exactly, people are too stuck in this "BF is just like COD now". Go and have fun your own way on Battlefield 6, who cares for K/D. And again, if people don't like the game, just don't play it, don't buy it, don't spend your money and time on it, you don't have to; go play something else that you actually enjoy, complaining about a franchise that you liked 13 years ago is just a waste of time, things change.
I myself have my critics against BF6, but overall, it is finally a good/decent Battlefield game. The issues we have at the moment are easy enough to fix.
