I'm in total agreement. I feel as though MyPlayer should be completely offline compatible, as I have no need of playing against anyone but the computer itself. I've always understood not having the option to play Online Association without an internet connection because, well, the idea of such a mode doesn't make sense without an online connection. But I don't understand making an offline mode unnecessarily online.
Unfortunately, I'm not always online, so the offline mode for which I'm attempting to progress is going to suffer in those instances. And certain aspects of the game not involving playing against anyone online won't even be available in the first place (no VC, no ability to edit MyPlayer).
