I really like the Physical and Magical Armor system. Moving away from Willpower and Bodybuilding is a good move. Without RNG you have more control over the course of the battle moreover the Armor system prevents the insane 2-3 turns game ender of Crowd Control + Burst dmg spell/skill spamming combo in D:OS. Fights are now comfortably longer, well paced and especially more tactical, requiring much thought and planning.
That being said, i wish damage reduction and blocking were still major mechanics in D:OS2. I feel that DR and Blocking from gear should go hand in hand with the new Phy/Mag Armor system. It adds another layer of min/max and strategy. It might make DR and Blocking OP but i'm sure it can be balanced down eventually.
