I think I figured something out. BFS introduced upgrade to NBC abd EBI, but not nursery. An iceberg in upgraded breeding site takes slight than 6 hours to breed, but takes 8 hours to incubate. Most players do not like seeing dragons idling in the breeding cave after breeding completed. Therefore they/we use gems to speed up incubation. This is nother trick to lure us into getting used to spend and buying gems.
