Why does bf make changes to make it worse.

Ive played bf since it first came out. It seems like every-time a new game comes out they get farther from the last. Like why take the good things and throw them away? Tank play was good in bf4 and other games in the series and now in bf6 seems like garbage. Flight mechanics were better in other series as well. In Bf5 you could build defensive structures it wasn’t perfect but they just gave up on that in total now. Stupid challenges now try to make you play their stupid game modes you might not even like. Also they give a ladder in assault that was cool in the beginning to get you to places that were cool. And anyone with a ladder could also get to the same spots but no lets nerf it so it makes the tool pointless. Im to the point where this series is dead and its just a mess everytime a new game comes out. They get farther and farther away from what makes bf bf. Stop trying to make it more COD and just make bf bf. More the game feel like something else the more you make it like all the other crap out there. Im honestly thinking of leaving bf altogether cause everytime a new game comes out it feels like a whole new remake that seems like it is farther from what bf was.
