Yes, as defensive units, minotaurs are quite good (if you need to protect against witches or assassins from larger creatures). On their own, they are weak as guards for mines or passages; it's easy to break through them, but their stats are strong – quite a paradox.

In my opinion, a good defensive unit should at least trade favorably with attackers (i.e., fast units). That is, a unit that attackers might be afraid to engage. A rare example of such a unit is the dwarven warrior.

Minotaurs have weak stats, considering their growth rate. Only their health is decent.

It's not for nothing that the mod description includes links to the review. There, we analyzed all the changes in detail with detailed explanations.
P.s. For the most attentive, I will duplicate the links to the reviews: Review of the "Alpha" version of the mod and Review of the "Beta" version of the mod

The video review lasts 4 hours, which is a long format and may not suit everyone. Especially for a mod with a relatively small list of changes. If there were a concise text version, that would be nice. But who would bother? :)
