huskarls x hand canons (about a group of 20-30 hand canons will do) and don’t fight directly with the champions, aim for the archers with the huskarls but attack the champions when they attempt to attack the hand canons and retreat the huskarls as soon as the enemy attempts to attack the huskarls with the champs and rinse/repeat to keep them harassed and keep a constant threat on the archers with the huskarls while taking care to micro the hand canons to stay out of range of the archers and make maximum damage against the champions. You are well and able to do exactly this vs teuton infantry - heal your huskarls with herbal meds, build a town center or two and/or a castle on the front lines for the hand canons to retreat into as well as for consistent healing for your huskarls which really should mainly be focusing on their forte, harassing archers and deleting buildings and luring opponents into unfavorable fights by the temptation of being weak in melee vs melee and lead the opponent into a harsh reality check with hand canons, well positioned and fully garrisoned castles with full attack upgrades, etc. Use bombard canons as an additional harassment device to foot archers.
My advice, don’t flood; use your units to the best of your ability, heal often and your discounts will be favorable for the long game, while ensuring to get those relics and keep your death ratio as low as possible and fight smartly.
The huskarls are anti archer Teutonic Knights; treat them with the respect they deserve and heal them often. Avoid melee fights like tk’s avoid archers, but as tk’s sometimes find the correct times to attack archers so will huskarls in melee fights.
Use bombard canons and skirms vs pesky cav archer groups or horseback ranged units in general and keep them at bay with the huskarls to help keep them from sniping the bombard canons, and tho you don’t have siege engineers, feel free to add in 2 onagers as insurance to prevent dive bombing without cost.
For taking on paladins; use pikes and defensive structure to the best of your ability and keep your eco well defended to the point you don’t need your military there. You can’t stone wall, but you have fully upgraded building armor and attack - consider outposts and other buildings as walls if needed, and be ready for anything, and even if it’s weak, palisading your castles can save it from destruction; use multiple layers if you have to.
I personally use these types of layouts, but minus 3 exterior farming directions; however 5 castles is well and doable, and you are well and able to make-do with only one. The inner castle’s double layer farming square is enough for 48 farms, and adding in an additional castle+ 2 tcs allows for 70 or 72 total or a little more. It also allows for a safe place to keep your relics in a preferred side of the 4 gated areas in the center castle’s shadow.
Being the first to buy 1500 stone from the market as well as gaining exterior stone areas helps to keep enemy stone structures down and more costly for them in the long run to replace and repair, I suggest also being the first to sell wood and food at the most opportune times to replace gold lost from buying stone or rather to go towards buying the stone later.
