So, what if you can make breeder? Maybe a little extention island that has a place to take dragons and create hybrids from a hand selected amount of dragons. Let just for example choose,
Now, there can be hybrid between any these dragons, making at least 30 different hybrids. Every time you update, you could add one more dragon or two, giving us new dragons to create instead of just searching. Maybe have some sort of special breeding fruit or fish required to for the breeding process. I think hybrids would make this game far more interesting.
