Okay, I know people have wanted this and some people haven’t. It’s a little controversial. But maybe there could be different types of dragons, like ice, fire, earth, water. They could each only spawn in specific biomes that match their type. I don’t know what you could use to tame them, but we need another form of transportation with animals other than horses and pigs. I know ostriches are probably coming into the game, but we don’t have any flying animals to get around on. Maybe you could also train the dragons to have better attacks? Just an idea, let me know who agrees and please add on.
I dislike this idea, dragons should be not a common occurance, the ender dragon is the final boss for pete's sake. Plus you can just use an elytra with fireworks to fly around, no risking an animals life if you crash needed.
