I have been throwing around the idea for a while, but I think this game really needs a trait that counters true damage. It would instantly rebalance all true damage teams without the need to nerf.
Trait: Holy Armor
Effect: Causes true damage to hit armor first for the troop with the trait.
Troops to get the effect:
Scared Guardian in place of Armored.
Valor in place of Armored.
Zephyros in place of Giant Bond and moved to the last trait.
For devour, simply make big, large, and immense troops incapable of being devoured.
