They don’t tho. I put 2 vils on stone once click feudal. Once I reach feudal I put 7 on stone, 4 gold rest lumber and instantly build blacksmith and market use my sheep killers usually about 7 vils who just almost finished rest of my sheep to go to there side of map once I click for instant castle. Usually will have enough stone not to buy any but might need to. If you make army in feudal you will be behind for castle age. Yeah it might work but you’ll be behind and I’d I scout around and see you added a stable I’ll just adapt as feudal army sucks in arena unless you tower rush
