minecraft better updates

Im new to this but i hope all you minecraft fans like it.

What ive been thinking is after a wile regular minecraft gets very boring and you will try to download mods textures and stuff like that. But what if minecraft added knew structures and mobs that would be awsome. What im thinking is minecraft should add castles,prymids, ruins, underground citys, and like mummies and other mobs to go along with it. It would be a great thing to do. it would make minecraft more popular. If u ever download the creeps and weirdos mod thats a great example of what im talking about they have prymids and castles and more mobs!!!! If u agree with me please comment with your ideas. :)

thank you and
sorry for my misspelling
