Don't get me wrong, more HP and Armor is always good, but talking like 25% dodge is "Average" in a raiding environment is absurd. Self buffed I have 42%, admittedly I have some T6, but my numbers with starting Kara T4 weren't nearly as low as 25%.

I was tanking Maulgar/Gruul before the massive armor buffs hit us, trust me, you don't need armor cap.
