Queen Chrysalis is a Hero for Fighting Starlight Glimmer, the agent of bolshevism in equestria, and though the reasons why she fought were at times petty still though were there times where her cause was just, She still has done more against Communism and there Jewish overlords than everyone on this board.
I wish s9 devoted more time to the antagonists, they were the only good thing about the season. More Cozy-Chrysalis interactions could have been fun. On another changeling-related note, I wish changelings filled the spot of being memed as the kikes of Equestria instead of gryphons. More potential for "How do you do, fellow ponies?" memes.
In the AU where FIM embraced tying seasons together with an overarching theme embodied by the villain (a nice compromise between episodic story structure and a continuous story split into multiple episodes) there was probably a season full of Changeling problems, some caused by Chrysalis.
