In before happy shits on this game for being a grindfest
diablo 3- the game where you spend all your time looking for better gear so it will be easier for you to find better gear.
Diablo 3 is essentially a single player co-op at this point. There's no reason to interact with another human being whatsoever.
Thats always been Diablo multiplayer
Nope. Diablo 2 was hard and you needed help.
