I'm going to be upfront and say I hate the armour system of DOS2. I found the combat of DOS1 was far more exciting than in DOS2 for this reason. Magic damage feels completely useless in comparison to just running a full physical damage party, so the excellent party diversity in DOS1 is wrecked in my eyes.
For whatever reason, it seems that RNG has been shunned in this game, but it was the balancing factor. Every single fight feels the same now - charge down enemies armour and then chain CC them.
