I kind of wish they'd change the Physical and Magical Armor attributes so that, instead of just increasing however much you have by X%, they make it so that Physical/Magical Armor increases your resistances to damage of those types. There are already very powerful ways to increase your Physical/Magical Armor in the forms of fortify and magic armor, both of which become more effective if points are spent into geomancy/hydrosophist respectively.
I don't think that requiring those very specific schools and that very specific spell should be the only way to increase the amount of physical/magical armor.
It is actually HILARIOUSLY ironic!
Given that the biggest gripe the development team had about the first game was how "Overpowered" the shields are.
So they remove them in Enhanced Edition...
Then what do they do in Divinity Original Sin 2? They add the exact same thing! And better yet it is the only way to have halfway decent armor and magic armor.
