Many (myself included) are reporting massively improved results regarding servers, rubberbanding, lag, etc. on both PS4 and X1. I played naval strike maps all evening on PS4 last night without any issues, it was great.
There was a minor server update yesterday, and Dice also announced that they were going to start resetting all servers weekly, but many think there may have been a quiet implementation of new server hardware, as someone at Dice tweeted they were getting new hardware for PS4 a week or two ago.
I'm hoping the improvements remain, I had an absolute blast rocking the AWS on the Naval Strike maps! Nice to finally get to enjoy those maps without raging!
