What would you add to Heroes? (creative ideas only!)

Neutrals are like the elves (all of them), until the world is completely ruined, and then the Haven faction has to do all the work to clean it up:mad:. But then, when something happens, they are always there and play the main role in saving the world! But that's just my opinion:o. In general, it wouldn't hurt to create a tech hero for Haven, with bonuses to armor and/or damage during sieges. After all, they are a technological race. And it would also be good to give the demons some kind of "Destroyer" unit with bonus damage against armored units (or something else);).
