I've had 2 Blazers with 35's. I replaced the ball joints on the driver's side of my '69, but I never had to do anything to them on the '72 I used to have. I don't know if the ball joint's on my '69 went bad because of the tires or just because of age. There are plenty of people running 35's and bigger on their blazers. I wouldn't think that going to 3/4 or 1 ton running gear is going to make too much difference in the ball joints.
