Good point @Aelthwyn. That reminds me of the line in fight club that if you take a long enough timeline, the survival rate drops to zero.
I don't see #1 ever happening for Unrepentant. #3 top, maybe in a 18-24 months. I guess it's not just people who reach the top, but also people who find a state of equilibrium and stay about the same place that sense of progression.
We're on a pretty complex hamster wheel though, so there's always another shiny to draw our attention. My current obsession is finishing traitstones. That'll hold me for a while.
