The armor system is actually quite fun and I don't understand the thing about people saying you need to stack a single damage type. Enemies most of the time have huge differences in armor so you have to focus different targets with different types of damage which actually makes it more tactical than just focusing everything on single most dangerous target every time. I'm running a 4 elemental school spellcaster, a huntsman, sword and board guy and a scoundrel and so far I haven't been cockblocked completely out of the game at any point on tactician.
The bigger issue with the whole combat system is CC being ridiculously overpowered. When you have mobs with 5k health while rest are usually in 500-1k range there's not much to do except to burn the armor that's lower down quickly and chain spam CC on the enemies. Maybe it's simpler on lower difficulties but that's my experience in general pretty much. The game would benefit overall more with a nerf to all kinds of CC effects while reducing some mob power levels.
Either way, I enjoy the combat system much more compared to OS1 which got really boring in the end game. Especially the spell variety is such a god sent, most of the difficult fights require some real setting up to deal with which is quite fun as well.
