The current meta is actually evolving into a completely different direction.
Away from big Army balls, instead attacking the opponent from multiple angles and raiding all over the place.
So currently CA have it kinda hard to compete.
I recently saw several games where the pros just completely raidet CA civs to death in the lategame.
The issue for the CA is that they need one ### #### of like 40-60 CA, then they need at least 20 Hussar in front at all times which also occupies at least 10 more pop space. Then they only have 110 vills which means when they lose 30 vill to raids they have a big issue with sustaining the hussar stream, especially if they need to replace these vills asap.
I agree that HCA are the strongest lategame unit. I also made one unit designed to counter that HCA + Hussar unit comp specifically.
