Really nice.
It seems that permanent armies will be scarce until midgame. A question comes to my mind... what happens with provincial armies? Will we use legions for that (when available)? Or will the figure of provincial armies as we currently know it disappear?.
I had the same question with the last DD. It seems they've been superseded by levies and legions, which are both province based. I'm assuming they're not going to be a major source of unrest reduction in 2.0 if at all. I don't think that's a major issue though, as long as there is some re-balancing to make up for it. Though it would be nice to get some new tools to deal with unrest instead.
