I didn't realize Helia was once supposed to be a druid rather than a bard. I'd always been opposed to Helia as a werewolf bard, but a werewolf druid? Completely fine to me. Maybe it's just that the druid and werewolf stuff feels like there's more synergy there than random werewolf plus bard.
A character that can shapechange playing a class that can shapechange is redundant.
