Not fun. Tried only because I was a fan of d2 back in the day.
Player dies not because of a great AI and interesting mechanics, but because of disconnects and issues with properly seeing what is going on in the game (effects land on each other, UI cover something).
Poor balancing and any player can also see it while playing. For example, let's say you are playing as rogue lvl 55 you jump from 1 location to another to stay alive, then comes a necromancer lvl 45 and spams his bone skill with eyes closed.
Cinematics are great tho.
