i did a test with the porcelain tower the gather rates are:
All resources(.5 i think) + .18 export + unknown exp/s
3 food /s 2.5 wood/s 2.5 coin/s
All resources(0.75 - 1.0/s i think) + .25 export/s + unknown exp/s
4.5 food/s 4 wood/s 4 coin/s
All resources(1.0 - 1.25/s i think) + .4 export/s + unknown exp/s
6 food/s 5.5 gold/s 5.5 wood/s
All resources(1.5 / s) + .5 export /s + unknown exp/s
6.5 food/s 6.0 wood/s 6.0 coin/s
china is op with trickles because they can get 5.5 wood/s(age 4 built tower) + 7.30 wood/s(factory from Russian consulate) + .40 wood/s(sutumptuary laws card) + 1.5 wood/s(German consulate trickle) which is around 15 wood per second which is pretty good, especially in long games. they make even more with food
The only thing I'm unsure of is the All resources setting rate for the Wonder(exp + resources), so correct me if you know the answer
Also, to the poster of the thread, i think they do that because they do not know that it gets better with each age. In this way, they are ignorant and usually wonder how their economy isnt as good as it should be.
I don't play on eso anymore. Gameranger and Hamachi.
