Dortmund, albeit having brought in very good new players (kagawa, lewandowski) and with their young playres seemingly developing nicely (sahin, götze, grosskreutz, hummels ...), will imo face the consquences of playing in the EL somewhere through the season as they have prolly the most working-/running-intensive approach in the bundesliga. And they didnt learn to safe their energy during matches they already won, like during the 5-0 trashing they gave Kaiserslautern midweek, when they kept on fighting with all their power until the last minute. Thats great for any spectator but just not efficient.
