I had an idea about a "green fire" quest for druids. Estetics only.
The animals forms (cat and bear) will change to more humanoid-like forms. Recommending the male and female worgen skeletons as base model, slightly altered ofcourse to fit cat and bear and not look like worgen too much. For the cat mode, the model of that cat boss from Zul'Gurub looks pretty good, ofcourse it will need some tweaking.
This will also help with the whines asking for female druid forms.
Obviously you can turn it off if you don't like it.
