Leaving things out

Minecraft is an amazing game but Microsoft is leaving a lot out of pe such as villager classes like fletcher or weapon smith
Their are only the base classes which are librarian, farmer, armor smith, and priest. Another thing they left out is different sizes of world because its virtually impossible to find strongholds on survival, its hard enough to find them on creative, since old worlds dont have them. In conclusion, Minecraft would be much better if these things were added.
