I played the first 18 ages and just come back. From what remember you either attacked or explore a T/M.
Having been out of protection a couple of days suddenly realized how hard it is when your in a crappy kingdom to grow as an attacker. Doing some CB's most people seem to have at least 50dpa and about same Opa. I think by the time I get my province into shape most people probably be around 60/60.
Anyways my point is to run a good province you need to sacrifice things like money/scence, which in turn means you can't grow as fast, and probably be lucky to hit once every two days.
Anyways running the numbers I could easily explore 10% of my land everyday keeping 90dpa 3 tpa/wpa.
Considering I'm in an inactive kingdom and small chance of war whats the point of attacking? I can grow 10% a day with very little chance of being attacked or grow 8% every second day with a good chance i'll get hit.....
