The way I see it, it does seem historicaly true to have people able to put a bit of copper on a bit of wood & bash peoples heads in, rather than on a small bit of wood then another shaped bit to shoot with. So I agree that achers should come after axeman.
What is needed is a basic defender unit that does not require any other building.
Perfect solution, A Slinger.
We know it's a very basic weapon, easy to use and very easy to make.
With a linger you can keep achery along same line as barracks, just have a axtra tech, or incorporate it into an early tech.
Make a slinger the same strength as a warrior, but it has a basic +xx% to city defence... or even +xx% to defending
(sorry if this has been mentioned, i've only read about 100 pages, this thread is TOO LONG)
But, GREAT MOD, Thanks
