Let me give you a quick example, 3v3 game. I’m HRE, I have a Chinese teammate and a Brit teammate. Opponent has 2 Chinese and 1 mongol.
I get to feudal go to the first Chinese players base with man at arms and archers to harass.
The mongol player now send mangudai to my base to harass me. I start to make outposts while still harassing Chinese player 1.
My team mates hit castle. Chinese player 2 from opponent side gets castle. Chinese player 1 I am harassing holds while I get siege engineering and got 3 Rams. The now buffed ZhuGeNu mass starts hitting my archers, and yep they melt so fast cause feudal Chinese need a buff amirite? I withdraw and get to castle, at 15 mins there are now 4 people in castle age and myself and the other Chinese player on their team are in feudal. But his zhugenu actually are busted and kite my MAA for days while I’m trying to take out his landmarks. He suddenly gets to castle cause he makes a landmark in the other Chinese players base.
I’m starting to build stone walls now that I am in castle but hold up the other Chinese player gets to imperial, my team gets to imperial. I’m clicking up. While stone walls are going up. China player I was harassing finally gets to castle. Teammate China player gets hit by 3 bombards and 30 fire lancers (not even elite and no upgrades) mangudai rush in first, in sending my landskents over to help deal with siege, by the time I reach there, the other China player on my side is gone, the China player I was harassing finds my lone landmark that I built at the corner with his 20 fire lancers and the Brit player has longbows all over the walls on our side, I start pumping out spearmen from my 22 barracks, China player busts into Brit base, no worries right? I should be able to brace their charge, easy counter, they ignore the spearmen and rush straight to every landmark in Brit base, they are losing people, but they manage to take out 3 landmarks, now there’s yellow firelancers, red firelancers, and cyan mangudai, 3 bombards, 2 mangonels in our base, I have 60 spears, 7 springs, Brit player has about 40 longbows and 3 mangonels, we try to back away.
Firelancers charge in and once again ignore units and go for my landmarks, I try to wololo, the charge explodes my monk. Game over
Edit: post game, they have 4 imperial officials supervising their stables built around a spirit way. Fire lancers have no reason to cost nothing to make. And it is easily achieved within 20 minutes of the game
