Its The Small Things
I noticed that in Lord of Hatred they give the player classes more of a personalized touch than in the previous incarnations of Diablo 4. Like your character is referred to as their class directly in some instances rather than just being The Wanderer all the time.
One fun thing I just noticed in my most recent playthrough of the story, I'm in the Horadric Vault doing the part in Jered Cain's Silent Scriptorium where you have to solve the simple riddle to progress. In my first playthrough as my Paladin, Lorath did all the riddle solving.
But in my current playthrough as the Sorcerer all of the sudden she's like "From whence comes the water? Oh this is a riddle that my clan tells to the children, the answer is Fire." Then she proceeds to finish the riddle for the group instead of Lorath. I just thought that was a neat little touch that makes the classes have a bit of unique flavor to them. Also a shout out to all of the amazing voice actors for our player characters, especially the Sorcerer. She's usually so soft spoken throughout the whole game, but when she gets angry in Lord of Hatred you can really feel it in the delivery.
What are some of the small details you noticed that made you appreciate this expansion even more?
