I love all of your characters, and I'd like to make a special mention for Isabela, because she's the one character most of the game is canonblind to and you always clarify she's more than the pervy act she puts on. It's easy to tell that much, and Isabela never struck me as simply a 2-D eternal dick joke. It's easy to tell she's smart and that there's more to her than that, even if the ridiculous perviness is hilarious as well, so I would say not to worry so much she might come across as flat or like a one-trick-pony.
That aside, I would love to see Korra being a little more proactive again. She used to address the characters as a community a lot more and she's been rather quiet, which is understandable since other characters of yours went through some intense things, as well as her canonpoint meaning she would ICly want to take a break. But she's a really fun and energetic leader-type of character, and I would love to see more of it.
