We have so much monsters, but only a little part of them are we able to get with breeding.
I know because of the free-to-play-thing u need a method to earn money.
But i think it will make the game for players, who don't want to pay so much, much better and raise the longtime motivation.

Cthulu, you need him to breed Netobus, but the only chance are gemstones, frustrating!

My idea is to make more old monsters able to get with breeding.
