so crunching the math japanese shrines (assuming kami + toshogu shrine + optimal hunts) produces either (at 20 max)
11.4 f/s or 10.1 wood or coin/s
torps ( assuming blueberry + Engelsberg)
10 f/s & 10.8 coin/s for about 13 mins before it runs out
China can probably match japan’s passive eco by age 3 tbh with the porcelain tower age up (EDIT: 4wood/s) + 1-2 consulate trickle (2 res/s) + summer palace (like 4-6 res/s)
and the torps all things considered ( its about like 35 vils worth of eco) is about on par with say the british house boom but you trade vils that are raidable by cav for torps raidable by pikes.
the thing with swedes now is how easy it is to get going with the boom and they become dangerous for a particular period, basically that 13 mins period where their eco will spike. which you can kinda see in their win rate with 45% of wins within 12-18 mins
that is true for swedes maybe but deflinte not for japan all data points to an inca comeback
