Ummm... I dunno. I think it was worthwhile to get the Breeding Tree for being able to run two Breeding Structures at the same time. Otherwise I would need two days per Pure Dark instead of two days per two Pure Darks right now. (Would have been great to be able to Breed three Pure Darks in 2 days, but no DBN for me. xD) Those of you who were at Lvl 10 and bought the DBN are lucky. I'd buy the DBN right now for 150 s.
