My argument, lore-wise, was that it's not his armor that gives him the bonus, but the fact that his body is made out of energy (equate it to water, hit rock with a pick axe and you will easily see damage done, swing that pickaxe at water in a pond and you won't actually see any damage). That's why i was confused, it seemed like you were agreeing with me, but I also got the feeling you weren't.

The water analogy is now better suited for Zac and his passive, but it works there as well.

And I personally think that Lore is a good excuse, if you ignore lore, then you might as well get rid of all the given laws such as gravity, colors, why there is a jungle with trees and a river, etc.
