In the interests of having an age that doesn't completely suck, I'm going to repeat my last post. These are simple changes that will have no effect whatsoever on kingdoms that don't grow, and will make growing a lot more fun.
* Leave dicing unchanged numerically, but have it all come out of the pool (0 or negative pool => 0 acres on a dice, or just remove the dice spell).
* Have the 10% winning acres also come out of the pool. If there is insufficient pool, lower the amount given, either across the board or by giving 10% to the smallest provinces first - or if that's too much work, just let the pool go negative. It's also possible to have these acres come out of the opponent's pool (in that case you should go negative to get them) and/or to remove the 10% gains you already get in war.
* Increase each kingdom's pool allotment to 125 acres/hour.
These are far from my only suggestions, but they are simple ones that nonetheless move toward a rational growth system whereby:
1. New acres should come from capped, persistent sources (currently dicing is not persistent).
2. War should be zero-sum (currently it is negative-sum, due to lost dicing).
