No I didn't. I already IGNORED this exact point
There, fixed it, at least its true now.
USF is supposed to have the strongest mainline. It does. That mainline is also more expensive than grens, who need a tech building
"Ost is supposed to have the strongest MG" is true. It has nothing to do with whether or not it should be the same price as the maxim, which also needs a tech building
I cant get even simpler to make you understand. Strong has nothing to do with costly. An expensive unit is less often spammed. A strong unit secures a game style. Strong TW encourages TW strategies. Strong Mainline encourages its use. Its a core unit. Just that.
It is not hard to understand it if you actually read and comprehend that this is not Age of Empiers.
Tech building is offtopic, it depends on the faction tech tree and limitations. Price does not determine performance. It determines efficiency and abundance.
