Appearance/discussion of Necropolis units.

Liches actually touch the ground. It's just that their "dress" hides their feet.

How can they not be visible? They are visible (I can see them).

In my opinion, liches are better than archliches (I don't like the horns on their helmet, and the color of their robe should have been red, not white).

Yeah, the dragons are weak.

That's not that significant. Although it seems like a nearly flying unit...
I don't have any similar complaints about the undead units (except for the dragons, but I've already talked about them many times!)

The strongest bone dragons were in Heroes of Might and Magic 4, and the spectral dragons were in Heroes of Might and Magic 3. But in Heroes of Might and Magic 5, they are weak, but their growth is higher than the others (due to the dragon tomb)
