I'm actually seeing the Amazons differently from the other inaccurate stuff. When an entire faction is inaccurate like the Egyptians, I don't like it at all. When it is a few units here and there like the headhurlers, I'm a little more ok with it as long as that unit doesn't dominate gameplay. If it's used occassionally, that's fine.

However, the Amazons are so out of the way that they're basically an easter egg. Easter egg's are put there by bored developers when they have a break. They're usually there to keep their sanity around. They're not meant to be in the spirit of the game because they aren't really part of the game in the strict sense. Warcraft3 had Starcraft units as easter eggs in various hidden places and you can't tell me that sci-fi units are not out of place in that game, even though it's all make believe.
