I think Feitoria pays off in somehing between 3-4 minutes actually. Included the housing space.
Feitoria ofc has the downside of occupying housing space.
But you are right 5 minute isn’t that long. Ii is actually shortet than the amortisation span of TCs. But also with the tweak, that TCs give so much more value in the long run in comparison.
Don’t know, I think because you need so many farmers to make it worth it, it’s still a very, very lategame upgrade as you will usually prefer to make military in the beginning of imp, it’s why you get up.
Also you maybe want to prefer flemish revolution, as it can give so much more value (also in terms of gold efficiency).
I think doing this upgrade earlier as when you see that gold becomse scarce is a waste, especially with burgundians and their whole design around their powerspikes.
