I for one really love the new Physical and Magical Armor Feature of the game. Makes it even better from my perspective. I wasn't a big fan of the percent chance to afflict conditions with the DOS Willpower and Bodybuilding. Nor did i like having to devote points into skills to up my saving throw chance. It took loads of skill points to develop those features.
Also i believe with the implementation of the armor system, it makes spells such as Ice Shield or Fire Shield and so on much more viable. In DOS Fire shield just made you immune to burning, where as in DOS2 You not only get burning immunity, but it also Adds to your magical armor. Making those spells more appealing to use. Plus, it's nice knowing your immune to conditions as long as you keep the specified armor up for the saving throw, another factor in making those armor boosting spells more appealing.
This is just in fact my opinion though.
