I'll give a thumbs up as well. I'm the kind of guy who likes changes, as long as they're interesting.

As for Vader folding his arms, you must remember, Vader never lies down, leans on a chair, sits on a table swinging his legs, covers his mouth when he sneezes, or anything. He simply sits or stands (or on rare occasions, kneels) with arms at the side, looking as tough as possible. It takes a physical toll, but it's the price ya pay to be cool. Besides, he has all those robotic limbs. No need to rest.
