Update normal dungeons

A lot of people have posted things related to update dungeons in general and I agree. But I think that the dungeon that most needs an update is the normal dungeon. They have been untouched since 10 years apart from loot tables changes. They should make them more detailed and a bit more bigger to not look like small perfect cube cobblestone boxes. They should also be a bit more varied like creating five types of dungeon rooms and each dungeon generates with 1-2 rooms to make each dungeon a bit more unique.
