The online worked better for me yesterday, had two games, no quitters and the game wasn't that laggy, not any more than fifa 11 to me. I lost both games, but it'll take time to get used to playing online rugby.
It is annoying that there is no ranking, or punishment for quitters, but i don't believe many kids of fifa age will bother with this game, so you should get a decent game in theory. Personally, i'll make a list (see my thread) and we can do it this way.
We can of course make our own ranking list, for TRF members anyway.
