>Could JKR do better with her worldbuilding?
This sounds like someone's homework.
Of course she could have done better but there are 2 things to consider:
1) her target audience was kids and their attention spans are usually shit.
2) they weren't important to the main story.
If you want to see world building at its finest, look up Steven erikson malazan book of the fallen.
all things considered her worldbuilding is pretty good
I'll go with the anime school of magic
