Ooooooh. Well yes, that is true. I don't think anyone was trying to dispute that though, I think they just took it for granted that that was the case and didn't really need explaining. I, for one, just thought you were debating whether the Elite 4 had anything to do with it at all. Obviously once you do beat the Elite 4 then you will have to connect online, otherwise how would the other person know? The key point though, is that you have beaten the Elite 4, not just that you are simply online whatever your point in the story. Hope that doesn't come across mean or snarky, I didn't mean for it too.
Well actually if you look back almost everyone who I was talking to disputed the fact getting online had anything to do with it all besides the special abilities. Most people said beating the elite 4 made the third pokemon appear not getting online, but it really doesn't matter anyway
