I've played about 80 games in FUT and not had a problem with losing connection to the EA servers.
On release day (29th), I entered my very first Draft and got disconnected from the EA servers within around 10 in-game minutes. I thought I just got unlucky and didn't think anything of it. Last night I spent 15K coins entering the Draft again to see if I could profit from the packs and got disconnected from the EA servers again, this time in the 90th minute when I was winning 4-3.
Every time I've lost connection to the EA servers, it's hasn't been due to my internet connection. All of my devices thought the house stay connected, and it's only the PS4 that 'apparently' disconnects. Immediently after losing connection, I've ran a network test on my PS4 and it doesn't seem to have a problem.
At this point, I don't really want to spend another 15K on a Draft entry if it's going to happen again.
Has any else had an issue like this, or am I just unlucky?
TLDR: I've entered 2 Drafts, and DC'd both times. The only times I've DC'd in over 80 games of FUT.
