yes it is wrong actually
Yamato and Assyrian villager never used that +30% for gathering rate, it is just for walking faster
So they chop wood just the same as most of the other civs, and mine gold the same, and farm at the same rate, etc etc
its just that they take the food back faster to the storage pit/granary/TC
and on another note I am curious to see if they reduced villager speed, the manual says +30% same as always, yet for some reason I just cant bronze in the same time as I used to be able to with them (it has been a long time but I can still pull a decent bronze rush )
