My problem with the breeding boost is that it does not remove common results from the results table. So, if you're breeding Sea and Terra to try for Plankton and you use the boost, the Mud and Waterfall dragons are still on the list. This makes using the breeding boost very unattractive. Had they programmed the breeding boost to give you access to a different results table, this would make using the breeding boost much more attractive and, I think, much more likely.
