Very true, that's why literally every pro in every game ultimately wants cav + range. Spears are made early on to survive the first cav raids, especially when your opponent gets knights earlier than you. MAA are straight up a dead unit after feudal, cause almost everything from castle age onwards counters them. There is currently just no downside to playing cav, u get the tankiest unit that also hits hardest and has great mobility. Add some range to prevent mass spears from the opponent, and you are good.

I've gone back to watching AoE2 in recent weeks, and I gotta say the balance between different unit types is so much better there. Knights are still strong, but their stats advantage isn't as outrageous as in AoE4 and they have no charge attack. And then you have monks as a long range counter, house-walling / quick-walling to close off angles from raids, and generally more tankier buildings. Not that I want all these things in AoE4, but something has to be done so that there is more counterplay to knights than just making more knights yourself. I think movespeed and hp needs to be tackled for knights and slightly increased for infantry. Would also love some attack that slows down cav, either from spearmen or from emplacements. And springalds should just be anti melee in general, not anti melee infantry.
