Why is Battlefield 6 getting increasingly unplayable?

Can we fully optimize Battlefield 6? This installment feels more like an online game than a proper large-scale battlefield experience—after all, a "grand battlefield" should live up to its name. Most of the maps in the current Battlefield 6 are confined to close-quarters street combat, and the whole visual style is a drab, muddy yellow that completely kills the epic battlefield vibe. It’s like the designers ran out of creative ideas entirely. Why can’t they take a page from Call of Duty? Just recycling popular maps from previous versions worked wonders for sales, didn’t it? Battlefield 6 could easily bring over fan-favorite maps from Battlefield 1, Battlefield 5, and Battlefield 2042.
 
Battlefield 1 nailed the grand battlefield atmosphere perfectly, a solid 10 out of 10. Even the half-baked Battlefield 5 still deserves a 10. And Battlefield 2042? If it weren’t for all those game-breaking crashes and bugs, it would totally outshine Battlefield 6 by a mile. People always say sequels should get better and better, so why has my beloved Battlefield franchise been on a downward spiral for two games in a row? I spent over 400 yuan on Battlefield 2042, and even when it was plagued with countless bugs, I never left a negative review online. I still held out hope for the next installment. But why is it only getting worse and worse?
