Pig attack and Pig Armor

It would be great that for mounts of mayhem, they make upgrades to pigs. So I thougt of pig armors. There would be for all materials except leather. When a pig has an armor, it has more health and can ambush forward, making area damage. The better the material, the more damage it deals. Its desing would have a Roman style in the pig's head, like a red thing that romans had on their helmets.
