Our entire group was constantly getting one hit killed as soon as we hit act 2, we did OK win act 1 with the odd death here and there from particulaly nasty elites, we went back to Hell after a few 8K+ repair bills but that's far to easy now.
That's probably where you're geared then. The "I can't realistically play there" cliff is pretty obvious when you get to it. Act II farming IMO is a major pain until you get to a point where you can get away from the bloody bees....
