I think it performs the concept "defense and breaking defense" very well.
If there's anything to recommend, I think it's good to convert Physical and Magical Armour in a 30~50% ratio when each of it is zero, before CC get work.
For those who argue about the CC problem or "Pure vs mixed damage team build" problem, I think the true issue is that for most of enemy in the game have element resistance and get no physical resistance, this is the balance I think DEVs should consider.
