Read my comment in it's entirety please. There's one very obvious improvement I suggest pretty much off the top of my head, I'm sure if you want to you'd come up with a dozen more. They aren't even trying.

I agree with you. There are several major games that transmit all player info at all times when it's really not necessary and makes "ESP" style hacks possible, which can be supremely unfair. Developers would rather tack on a rootkit than make engine changes to resist this kind of cheating.

Ok ok. Some are not even trying that’s true, but not everyone.

But when I try to play a battlefield game these days you often get hackers who can go really fast across the map. And detecting them sounds super easy server side.
