After the Fall of Beacon, characters who aren't RWBY, JNPR, STRQ or Ozpin are out of focus. With Sun making a supporting role and Neptune making a cameo, we hadn't heard of the other teams ever since Volume 3 (while Team CFVY is said to have an upcoming book about their adventures in Vacuo)

With Volume 7 on the way, I look forward to seeing old characters back. For sure, Winter will make a comeback and so will Ironwood and the rest of Weiss' family. I'm looking for Team FNKI's return and possibly Penny's team and her creator. I see it as wasted plot points since they didn't get to explore Mistral more and I hope Rooster Teeth learned from their mistakes.
