you can, I discovered this trick with hotkeys, so it does require some knowledge and getting use to
the build you kinda want to go for if its late game salt is the berber card which sends 1 berber for every outpost and TC, you can send it twice if you remember to send it before imp and potentialy max out on salt mine with berber vils
On the topic of hausa food i am more convinced now that lategame food ratio for hausa is like 80 food 20-ish on gold due to how low some of the gold cost for their units are. they also have the ability to task cows onto field for like an extra 5 vils worth iirc and you can build up a reserve of food using the Akan exchange tech
yeah and they used to be even more busted with 360 hp base and 1 pop lol
With fulani you used to be able to infinite kite against any melee cav cause they essentially snare them and you have a ranged mass running at like 5 speed.
with the age 4 card they can even support cav masses and speed them up even more
