Swords are useles units. They are only useful in the beginning. Later you need only spears+HC or archers+HC. But there is an option when building swords+archers. It takes twice more time to build but it is better (approximatelly 20% better) than spears+HC.
21000 farm space:
1.
2000 hc =12 000 f.s.
7400 spears (or archers) = 7400 f.s.
200 cats = 1 600 f.s.
2.
10 000 archers
10 000 swords
you might use such powerful defence if only you have more than 200 villages and your tribe has expanded to rim. Actually going through archers+swords is unreal because if your tribe is active so you will be forced to build fast spears+HC or if your tribe is inactive so another active tribe will not give you a chance to grow to swords+archer defence.
Offensive villages are simple:
1. hc strat:
11700 axes
1300 hc
300 rams
2. just nuke (prevuios (1) is a 90% sthrength of it)
4000 axes
3800 LC
300 rams
These are a units which you can easily build and spend all resources which you get from your villages. Every time you will need iron but it is the cheapest resource on market by the other hand LC is the most powerful units. You will not be able to build axes more than 7k in nuke because you will need too many wood btw it is the most expensive resource than is why you need to concentrate on infantry (spears or swords) and LC/HC. And one important notice: Mounted archers sucks both with swords its a useless units
