Elemental Pet Dragons

Hello, Minecraft Community and Mojang. I come to you with the idea of Pet Elemental Dragons. I speak to all Dragon Fans when I say this is needes in Minecraft. Reason 1. The World of Minecraft is very large, and it is hard to find a good method of transportation. I think dragons would be a good idea because you can ride them throughout the world. Reason 2. One thing that Mojang must be tired of hearing is we need new bosses. Well, Dragons would solve that problem. Dragons could be found throughout diffrent biomes depending on their Type, and there could be a chance to find a King dragon cave. Inside, there would be a King/Queen dragon and you could battle it for a Boss Dragon egg. Reason 3. Getting a dragon and/or a dragon army would be a great achievement in Minecraft. It could be a common goal, or getting a certain amount and/or every type of dragon would be a great achievement. Please Upvote my idea!! Thank you all.
