How about 200 damage and 7 armor reduction for 7 seconds?
Its alright i think.

1. Hero Suggestion : If there is a Hero needed to be added i recommend: Diablo... I was just thinking to add this hero on your list because since he is a part of blizzard. Diablo - Lord of Destruction is fitted for the place.. Of course the game masters will be the one to assign the skills and the likes. Skills like Apocalypse as the special skill knockback chance... Hellfire, Demonic Charge and one passive. Strength type maybe.. another is the name for King Leoric = Black King.

warrior have new skill 1) can absorb other heroes damage.
2) return hit to the enemy
