I was hoping the Berserker would get some touch-ups, since it's tabletop source can be a little underwhelming. The Totem Warrior -- or Wildheart, as it's been renamed -- features have also been altered a bit. The Bear still gives damage resistance to everything but psychic, and the Wolf can still give other characters advantage, but I gather they wanted them to have some more active options rather than just passive abilities. At least, so I assume.
