How do you all feel about the new units added to vanilla civs in TotD expansion?

To me it feels like many of the new units were added to fill tech tree holes that were there by design. For instance, the lack of a Greek healing unit. I think Greek players were supposed to rely on Techs, and Godpowers to heal their units. Similarly, the Atlanteans already have one of the best if not the best military, so it feels like them lacking in ranged anti-building siege options was intentional by the developers.

Granted, I'm not a very good player, so I wanted to know what you all thought.
