Rangers, Sorcerers, Wizards and Bards have Alter Self and can change into Kith forms. It would be good if druids had availability to some alternate forms that can talk - my take is that they are not overpowered in combat, especially when compared to other forms - they would primarily be useful for changeling trickery.
so the suggestion is to make Alter Self available to druids (perhaps at circle 3 instead of 2) or add these nine shapes to wildshape.

Dryad
Gnoll
Kobold

Sahuagin
Satyr
Troglodyte
Not necessarily overpowered, but there is a thematic reason druids turn into animals and not other humanoids.
