Did the first one really have offline? I played the shit out of it, but I was always connected. Sure, they should implement something similar here, too, but it is genuine work they need to put in to get it there, I'm sure they had to invest that for the first game especially since it was on the Vita.
It isn't arbitrary, though, go on any of the communities that care about the meta war and you'll see people really do keep up with it and enjoy it, they work with each other to focus on the major orders and do a bit of roleplaying at the same time.
I know that you're very anti always online, and I understand and agree that it should be optional, but to say that nothing comes out of it would also be disingenuous.
