So this is what one of my friends said in a chat and I thought I'd post it here:
To experienced players:
I have spawn and 15c capital now. I want to keep the three expansion slots of my 15c free. and I want to make one more village asap. which path I should take? shortest and economical suggestions would be much appreciated.
upgrading residence will cost me 700K any better option?
My second option, settle 3rd village from 15c. On the 3rd village, build MB lvl 5, RP lvl1, G lvl3, WH lvl7, Residence lvl10, train settlers and settle 4th village. Then I cata down the 3rd village to free the expansion slot on 15C. It cost me only 104K. Am I doing anything wrong in my calculation? Looking forward to the input from you guys.
Also, I have heard people saying that you can use a chief to move used expansion slots from one village to another? Although I don't know if this works against a capital.
