Battle of the Celestial Gates

In most videos, the heroes speak with their mouths closed. This is a "feature" of Heroes 5.

This feature was only in the basic Heroes 5. But there were advanced animations, and the technology for creating them has been lost! And in the add-ons Hammers of Fate and Tribes of the East, there were no longer advanced animations, but everyone opened their mouths. There are 2 parts of the heroes where the characters speak with their mouths open, and 1 with their mouths closed, and I believe that a feature of the minority cannot be considered a feature.
