There are some slight balancing issues in the game. The Wizard can get away with almost anything, thanks to a combination of ranged damage spells and crowd control. The Barbarian, on the other hand, needs to have great gear to survive the second of the four Acts, where the difficulty suddenly spikes and melee classes will always be taking damage.
That said, the game is clearly structured around multiplayer. Every game is played online and even if you switch off the "open session" that lets your friends join you at will, it will default to being open again next time you play. It's easy to get a multiplayer game and the random nature of the loot ensures that trading items gives everyone an advantage. It is impossible to play offline, even if you have no interest in playing with others. You simply cannot opt out.
Another thing you'll need is a server; something that was (reportedly) unreliable for many during the launch week. I played some 30 hours, but forums around the world were ablaze with complaints. I have zero doubt that any issues that remain will be resolved.
Blizzard haven't set out to reinvent the wheel with Diablo III, but to release the ultimate wheel. If you expect something different, there's a real chance it might disappoint. I plan to play this for years.
