Flemish Revolution feels really imbalanced.

I've seen a few players use Flemish Revolution. Most recently in a 1 on 1. I ended up winning but, I am really amazed at just how overpowered this tech is.

I watched a spirit of the law video on it https://www.youtube.com/watch?v=sTNeGAvkqbQ and he explains that if you have 100 villagers, it's only 4.5 gold per unit. They (generally speaking) have the strengths of champions plus the strengths of halberdiers, together in the same unit.

The loss of economy is kind of a non-issue. If anything it works the opposite. It's a gain in economy. 100+ strong units for, something like 4.5 gold each, is like getting hundreds (thousands?) of free resources. When I saw my opponent use this in my last came, he rebuilt his villagers in only minutes.

I saw this stat that, the tech only has a 20% win rate. I honestly don't know how that can be the case. Perhaps the people who are using it think they can just pay to win, by buying this overpowered civ.

It kind of made me feel a bit sour about that match. I am honestly amazed that I won, but if I hadn't, I don't feel that it would have been a fair victory for my opponent. It would be one thing if these were like, 100 cheap weak units. But they are so strong that, in a lot of situations, there's not much answer for it.
