It was tamed down, several times in fact, but they can only do so much. You have to keep a certain range of motion or it becomes a waste of the ride system. They were already refraining from having it do inversions, something it's entirely capable of doing in too many ways to count.
I know that I personally was extremely nauseous the first time I rode. Now it rarely bothers me.
Giving some vehicles a less intense ride profile than others isn't an option, as it would destroy the ride's capacity. It doesn't have two separate sides a la Mission: Space.
God i wish it had inversions like corkscrews on broom sticks.
