EA please explain

I spent a couple hours playing the game...

Hitting someone hipfire with the CAR in Wildcard, fully shielded, it knocks them. Without fail, a fully empty equalled a knock.

Then, in the subsequent hours

Now even players without shields, are taking a full hipfire CAR, I reload, hit them with another hakf a CAR, then they down me.

How can that be happening so frequent and differ so frequent from the previous experience. What is causing that???

I checked the Packet Loss 0, the Ping 42ms, IO 40/10, FPS 60

this is consistent whether the good gameplay or the suspect one.

PLEASE explain what is going on. There is no point playing this game if every opponent is essentially immune or takes double the damage to kill. It’s ridiculous.
