Poll: Do you think games like Diablo 3 should be constantly tethered to a service?

Diablo 3 was just launched today and to play, you’ll need a constant and steady internet connection to battle.net. I don’t mind having to have a system check in once in a while like how Steam does it, but the constant tethering to Blizzard’s servers for the single player mode is a bit much for me, especially with the shoddy internet connection in Canada. So what do you think of the need for games like Diablo 3 that need constant connection, even if you’re only playing the single player mode?
