I love Divinity Original Sin 2 but I absolutely think the combat has a lot of problems.
The biggest one for me is that enemies are either too weak to be challenging or they are too powerful and the fight against them becomes a game of waiting who dies first.
The difference between these two extremes is the player level.
Enemies which are more than 2 level higher than you are so much stronger than you that fighting them is pointless, it is not even impossible but it is boring since they take so many hits before dying.
Also the inflation is insane I once found a piece of armour that had the double amount of protection and was only one level above my current armor.
Also I would say that combat now feels slower than in Original Sin, but I am not sure that´s because of the armour system (which I like) or not but I am absolutely sure combat feels less rewarding to me now.
I really hope that Larian fixes these issues in order to make the combat as good as the story and dialogue.
