Not really, since the boost only counts as an temp level boost that get used to calculate the rate. For example: Earn+EarnB*(lv-1+5). This way you have more chance to unlock all dificulty 3 slots. You need an rate of 1000 in order for unlocking all slots. An example between Gummy and Cool Fire level 30: In the base with this example the boost will have no chance for unlocking another slot since you need another 100 for the 4th one. The only thing that the boost in this example will do is increase the chance for an dragon listed in dificulty 2.
 * without boost +  =
 * with boost +  =

So in onder to make best advantage of the breeding boost your dragon should have an so high base earning as possible. The cool fire dragon only has an 5/3 earning so your dragon on an legend dragon is an lot lower than if you use an armodillo lv 30 with gummy: It will unlocked another slot so your chance on an legendary increase.
