I too identify with getting older being at odds with frantic multiplayer fps action and I don’t expect myself to have any form of decent K/D ratio anymore, but the nice thing about BF is that your score isn’t tied to making kills as much as its tied to playing your role well.
I consistently end up in the top of the list by healing and reviving or providing ammo to squadmates.
Another thing is that once you start rushing and sprinting all the time, your deaths will increase dramatically.
Use cover and slow down and the experience gets much better. I need to remind myself to slow down all the time.
But once I do, I get a much more fun match.
I am looking forward to BF2042 a lot! Finally a return to what made BF popular in its earlier days it seems. Lots of BF2 vibes here, sprinkled with fan service from the range of the series. Happy so far!
