More fleshed out idea using willpower conversion:
Druids don't get a racial bonus (+2), but instead choose a totem. The totem affects the druid's stats in all forms and serves as the "primary" designation for that druid: Druids of the Claw
Bear Totem (+1 Str, +1 Con)
Cat Totem (+1 Dex, +1 Has) Druids of the Talon
Raven Totem (+2 Wis)
Owl Totem (+2 Wpr) Other totems?
Owlbeast (+2 Str)
Snake (+2 Dex)
Stag (+2 Has)
Boar (+2 Con) Wisdom Conversion
The druid's primary casting stat for adopting forms and casting offensively is wisdom (max 5 unbuffed at char gen).
1. Switching between forms - including humanoid and animal - will take a full combat turn, if it combat.
2. When the druid is in a different form, their wisdom stat gets converted directly to the stat corresponding to that form as follows:
Bear -> Str
Cat/Snake -> Dex
Travel (Cheetah, Stag) -> Haste
Owlbeast -> Con (Only increases potential maximum HP, does not add to current)
3. The druid is assumed to have naturally 0 WIS and 0 WPR in all animal forms, though they retain any bonuses they gain from their totem.
