I just played 2 matches online...(well 1 and a half). Both games i went in to were 5 bar connections.
The first game i was 12 3 up, coming towards the end of the first half, i kicked to him to restart and the game paused (assuming he paused it) then connection lost. Im guessing he left match.
Second game i played against a french person, completed the whole game i won 17-5. Like i said, great connection going in to the game, but the lag was once again horrible, the buttons have a few nano seconds delay, so when u move analogue for your player to change angle of running, he moves nearly a second after, tackling is an absolute nightmare. Its nearly impossible unless you let the CPU make the tackle.
Every single game i play online is like this, its terrible and really annoying. I enjoy the game so much, and really want to play online, but it is a massive put off when the lag/delay is so bad! There is probably thousands of people online at once for this game, surely there is good connections somewhere.
