In Diablo III, my wife and I really loved the unique way we were introduced to our class. Sure, every story was the same but the intro with the simple drawings detailing what the Crusader went through and why they were doing what they do, it gave you a wonderful feel for the character.
So far, in Diablo IV, it plops everyone down the same way. Sure, we love the opening cutscenes, and each class going through the same thing once the game starts off works wonderfully with how they have done the cutscenes now.
However, we need a bit more to get introduced to the lore and story behind the class we are each playing I think. We’d love to see specific intros in some way to each class from a lore and story perspective, and feel that doing so would add just that more attachment to our chosen character class. It’s a win/win for Blizzard!
