We didn't see a big rotation from Leverkusen in their DFB Pokal game against Paderborn yesterday. The strongest rotation was in the defense line as the goalkeeper and defenders were all different than their previous league game. The rest of the lineup was pretty much the same. They got a decent win and moved on there.
Stuttgart played a much more difficult game against Dortmund on paper. However I was still expecting them to eliminate Dortmund and they really did it.

Stuttgart are in a better condition than Dortmund now and I expect them to be very ambitious in the DFB Pokal cup as well.
