Try 2 Barracks Supplies M@A against full wood walls, at least in very open maps or lower ELO. 10 or more M@A is the bare minimum critical mass to reach, as 10 M@A on any non-TC Feudal Age building will quickly tear it down, even without Forging. Out repairing 10 M@A won’t work either, as it takes 4 Villagers to do so + so much wood that the defending player would be better off letting the building go and rebuilding elsewhere. Unless the defending player full Stone Walls, a 2 Barracks full M@A rush should break in eventually. Here’s the build I’ve been practicing as Byzantines, usually without pushing deer, for a generic Dark/Feudal Age:
6 on sheep.
4 on wood.
1 lure boar.
4 on berries.
+1 on boar.
+2 on wood.
3 on gold.
Research Loom, then research Feudal Age.
(22 total population.)
While advancing to Feudal, build 2 Barracks. Upon reaching the Feudal Age, idle your TC, research Supplies and Man-at-Arms, build a Blacksmith to research Scale Mail Armor, then start making M@A. Your main target inside the opponent’s base is keeping them off of gold, then stone, then wood. Use your M@A to destroy Mining Camps and Lumber Camps. When you have at least 10 M@A, you can also destroy military buildings.
With a generic Dark/Feudal Age civ and without pushing deer, there will be a temporary lapse in constant M@A production as your sheep Villagers transition to Farms. Pushing one deer helps with this. But pushing two deer opens up the option of adding one or two Villagers in Feudal before idling your TC, or adding Forging with a temporary lapse in constant M@A production that is the same as not pushing deer.
As this build was discovered with the Byzantines, any civ with Supplies can make this build. But Aztecs, Bulgarians, Burmese, Celts, Goths, Incas, Japanese, Malians, Slavs, and Vikings will get the most out of this build. Though for myself, Vietnamese is the most interesting pick, because their scouting bonus means your Scout could stay in your base long enough to push all deer, where you can then use the Vietnamese economy bonus to buy Horse Collar, Double-Bit Axe, and Gold Mining with 3 deer, or replace Gold Mining with Wheelbarrow with 4 deer.
