Body-roll and weight transfer are largely unrelated.
If you raise the roll-centre, body-roll will be reduced, but the same total weight transfer will still take place (in this case the load will transfer through the links and arms into the tyres). This load transfer is undamped, so too high a roll-centre will make a car very edgy, hard to drive, and prone to grip-roll.
Yea, well put. Though I think the practical implications vary depending on track surface. On most asphalt tracks, that are low to mid-high, I find that the higher roll center does indeed make the car react quicker, but doesn't necessarily go as far as grip rolling. I found it instead will overload that tire and cause a slide as the tire is pushed past what it can produce as far as traction.
