I love that special animation. It quite resembles a medieval knight and this reinforces my personal vision of Númenóreans in general, as much akin to Romans during the apex of the old empire or the noble kings of Middle Age (the Holy Roman Empire, mainly). I wonder whether that animation could find its place in the Edain Mod, serving another monarch in need. A woodland monarch, I say, who yearns a more kingly composure, despite the difficulty of finding something appropriate for the character.
As I have already told Fredius, the special attack of Isildur against the Dark Lord could be seen as a parallelism with what happens in the last mission of Age of Mythology: The Titans, in which the player is obliged to make usage of Gaia and her special attack, in order to vanquish Kronos. It might not be a very original of a solution, yet it's equally interesting to draw similar comparisons. It's by the hands of Aragorn's ancestry that Sauron fell, after all.
