I absolutely hate seeing other players in towns and in the world. I want to choose to be in a group. It really, really bothers me. It needs to be like Diablo 2 and 3. I really hope you change this.
The Necromancers skeletons are bright and cartoony. Diablo 4 has a very dark and gritty look to it, but the skeletons are just wrong (They are horrible looking in Diablo 3 too)
The cinematics, aesthetics, sound and music are great.
