WotLK Difference between NM and HC bosses in ICC on Lordaeron

[lifesized]

Apart from the mechanics, damage dealt by the bosses and HP, which are obvious if you pay attention to your UI, do the heroic bosses have higher armour and/or spell resistance? I was just wondering if it is fair to compare damage meters on a NM boss and on a HC boss.

I think all bosses regardless of nm or hc version, including the Lich King, has the same armor value and resistances if they have. Im %90 sure of this. And to question if its fair or not, well the longer you fight the longer you push yourself to maintain your dps, mana etc, I dont think it would be clean to compare even if fair.
