Warhammer Heavy Armor Tank stuff question

Hello Warhammer people! I have no idea if you have been surfing the net collecting facts about this game as much as I am, but I will be grateful if anyone could answer to one dilemma that still exists in my head cause I still havent managed to find the way to resolve it. I wonder if heavy armor tank stuff is being immune on magic attacks?

Hi mate! I am not sure that Mystic has reveled info how resistant armor will be in Warhammer so far, am I right? I know that in some MMO's heavy armor is being a great defensive thing against mags but I think in Warhammer it will just give you some points for health and defense, so being stroked by mag-attack means that you are losing points in both areas. I dont think any armor can make you immune on those kinds of attacks.
