ok where to begin first off you your walls require a workshop your relief station requires horseback riding, horseback riding requires a stable, a stable requires a level 5 farm so you'll need at least that. your troops also require different techonologies for instance ballista require metal casting which also requires a workshop.

So I'd take a close look to make sure you get what you need for your final product/technologies at the very least a workshop and i would probably build a forge to increase production speed. Also barracks have a diminishing return 1 barracks 100% 2 = 50% 3= 33% ect so 10 barrack = 10% of normal time to build units but by adding another 10 you only gain another 5% thus taking about 5% of the time to construct units instead of the 10%

So if you think it's worth it good luck and pass along your coords
