I got so many Crusaders! I dread breeding for the rest as he is my stock standard diamond fail. I did well over 200 tries for Quetzal I just lost count after that. I'm a bit like you - I am still resisting the Unicorn purchase, although I know I probably will buy the Value Pack. I don't mind buying expired dragons in value packs, but I like to breed the breedable ones.
Maybe I am just too impatient! I am sure they would all come to me in time, but a little boost is allowed, so I took advantage of the opportunity. Plus I was curious to see if it would make any difference.
Well done on your Diamond family!
