Oh and one last parting shot as I close this thread...(cause I can have the last word)
There are number of different "trade calculators" that you can find out on the internet...none of which are endorsed by or provided by Forge of Empires...they are simply some players thoughts on what a reasonable trade is....
Some guilds have decided to use them and even some players try to enforce those calculators as the "official trade policy" of forge of empires but that is not true. Just as the "fair trade ratio" found in the mobile app is also not policy but rather suggestion.
Most of those players who use odd ball calculations don't factor in the cost of producing higher age goods that require additional land due to two lane roads, larger goods buildings or in the upper ages additional lower age goods to make the upper level goods.
So we leave this great debate unresolved for now
