“Heroes of Might and Magic V: Tribes of the East”

I'm curious to know about alternative upgrades for Assassins, Hydras, and Black Dragons. Maybe they'll just change their color, like they did with the Outcasts? :)
What are your ideas? Share them:

What's wrong with the existing ones?))) Assassins could use some kind of subtle smoke effect or bloodshot eyes.))))) Hydras could have more heads, but they should stop plagiarizing the Necromancer's image.)))) Dragons could have a rider added, but I'm not sure!
