Useless or redundant units?

They're also one of the few Pangea units that can go toe to toe with other national troops and have a fighting chance.

The other unit would be centaur warriors, who have fantastically better stats and allow you to take a sloth scale instead of the production scale that minotaur warriors require.

In the first instance, it prevents them being swarmed and mobbed by smaller units. It's always nice to see a bunch of smaller units scattered by a charge of war minotaurs, and often the inability of the smaller units to mob up and reduce the defence of the war minotaurs is incredibly useful.

I'm not sure what you are talking about here. Trampling units get swarmed even more often than non-trampling units, because they move right into the middle of packs of enemy units and get mobbed on the next turn.
