I feel like the Zulu are really underwhelming compared to the other militaristic CBP civs. I rarely see them do anything but settle a handful of cities and stagnate. UA: Melee units cost 50% less maintenance, units require 25% less experience to earn their next promotion, and your great General Combat bonus is increased by 10%. The 50% maintenance reduction is okay. I've never personally had an issue with gold production a single time while playing CBP so unit maintenance is pretty basic. Additionally it's only Melee units which seem to compose less of armies outside the Impi rush stage. Less experience is good. The improved Great Generals is really nice, but coupled with the Ikanda is less so. All your Melee units end up faster than your GGs. UB: Nearby mines gain +1 production. Grants Unique promotion to all melee units, and reduces Crime Slightly. The unique promotions are nice. They are all useful and strong. The lack of the +15 XP compared to the barracks is a big turn off since that compounds making new units less useful later in the game. The +1 production from mines is nice but in the grand scheme of things is negligible. You can only afford so many mines being worked early game and by the time you can work a ton of mines the +1 production is barely anything compared to all the other things that benefit mines. UU: The Impi, replaces musketmen. CS is 30. Has a spear throw start and +50% bonus against mounted. Absolutely no complaints about the Impi. Meshes really well with the rest of the Zulu's abilities etc. Every time I see the Zulus go up against the other militaristic AI (Rome, Sweden, Denmark, Japan, Greece, Songhai) they get absolutely destroyed unless they are in the Impi stage.
