Why has it become so sweaty? netcode? hitreg?

Throughout Season 1 there were time whereby I'd be questioning why a player didn't die as I tried to eliminate him or being killed around corners coming into cover, but for the most part it wasn't too extreme. Usually I'd be up there near the top in flag captures and more kills than deaths. However something has gone drastically wrong in Season 2!

Bar the odd round, nearly every single one of them are filled with what I can only describe as sweaty lobbies. I'm putting a ton of rounds into people that wont die and yet I die in one hit. It feels like everyone is running around with a shotgun, but not so. As soon as I'm seeing the player I don't have the chance to react, it's INSTANT DEATH. One frame kills?

Other examples include seeing a player from behind, I fire my gun for a close headshot, no damage instant turn around and bang I'm dead one hit to a pistol.

There's also the killed into cover which has got so much worse. As soon as I think I'm in the clear, sometimes It would be a good min after going into cover and I'm dead from the guy previously shooting.

So now every server I'm struggling to even stay even! This is also affecting our entire team as well, with many of us just rage quitting when it gets really bad.

So what's gone wrong? Why are EA not making this a priority!

1GB Ultra Fibre, 6MS sometimes to the server, don't use WIFI and frame rates never drop below 160.
