Possible solution:
- Ideal provincial income remains the same (i.e. the square of the province level, assaumng max holding levels and no other modifiers). So a province 5 will be worth 25 Gbs/turn.
- Province/holding income is based on a divisor of 6, rather than 5. So each holding level will generate a little less income.
- Currently each of province, manor, temple, guild, trade generats an equal amount of income. Under the new scheme the province counts double.
- Taxes are reduced; heavy tax now claims on 30% (istead of 40%). Other rates changed accordingly; light only collects 5%, fair 10%, moderate 20%, and so on.
The net result is that province taxation becomes slightly more valuable (since they count double, they are now worth 2/6 of the province rather then 1/5). Holding rulers are not penalized: Net income is almost identical (small variations only, tenths of gold bars max).
The math is a little more complicated (not much) but it's handled by the P&H anyway, so no problem there.
Updating the P&H is also easy since we have moved to the new standarized format (thank Sarimie!).
No more money is generated.
