In Legend of Korra, it seems that Ba Sing Se hasn't changed much since the 100 year war ended besides that there is still the poor who live in the lower rings and the most important and richest of Ba Sing Se live in the upper rings close to the royal palace.
Not to mention a greedy queen that does not care in the least about her own people, the government or anything else. Not that Ba Sing Se is all bad. I mean at least the Dai Lee are better and are loyal to the current ruler.
So my question is, was there any other big changes or changes that occured in Ba Sing Se (Good and Bad) since the 100 year war ended and the Republic of Nations formed?
