no good build for you....

Try not to make fun of me to bad, I actually fared pretty well!
Oi you
Don't blame it on that though, you had the perfect troops to counter him actually /tease
I am not sure whose setup you were using, but you probably misunderstood the point of it a bit.
You went heavy in spear cavalry only to be dominated in mobility and went heavy in swords only to send them against shielded bows.

Basically, you lost on your right flank with one Great Guard and one Yari Cavalry against two Katana Cavalry squads which also trashed through two entire Loan Sword units because you could not multitask the charge.
Then you lost on your left flank with one Great Guard, three Yari Cavalry and two Yari Samurai against only two Great Guard, one Yari Ashigaru and one Matchlock unit by letting all four of your Cavalry units charged by the Yari Ashigaru. You could have retreated at any point even then, yet you preferred to take the melee against spears and clump all those horses together, and when he sent one Great Guard to reinforce the Ashis, you just piled up even more units when you sent in the two Yari Samurai without profiting from it to get your four Cavalry units out of there, where his single unit of matchlocks was tearing them appart. Needless to say all he had to do was then prolong this slaughter even more when he sent the second Great Guard and again pinned down Six whole units under matchlock fire with one single unit.
All the while, you charged the center with monks and swords into a spear meatshield which let his bows eat them whole.

If he would've scripted that in his favor, he wouldn't have done a better job
Just the cavalry maneuvers should give you the win next time if he does not change his setup, despite his deceptively strong veteran KCs. Or at least even the most basic ones would've made a big difference in this encounter if you would've attempted any Hope you don't mind the harangue, but you were such a meanie to those horsies!
