But that's the point... they were using them so much because they had become arrogant, that they could handle anything with their Jedi abilities. And that arrogance ultimately was their downfall, they couldn't see what Palpatine was doing right under their noses either with the government or with Anakin. I mean, I am no lover of the prequels but this was all spelled out pretty clearly, and was the story reason that they used their abilities so much. I honestly don't think George Lucas gives a flying fig what the fans want, and he has said as much. He just wants to tell his stories his way.
