I haven't experienced any host migrations yet, but the connection still feels "one-sided" at times. Especially on weekends when there are more players online. I thought dedicated servers would make the net code/lag comp better, but I haven't seen much improvement. Have dedicated servers been confirmed to be up and running now that the PS4 launched in Europe?
Edit: I know they're using the hybrid system of "Listen servers/dedicated servers". I just hope that dedicated servers aren't for coastal area's like NY/LA, with the rest on listen servers.
