I want the player to be able to choose any of the wildlife creature as their character. So with the character creation where you can choose your faction/race you should also have the option to play as a deer for instance. For the customization you could choose a different pelt, tail length and so on. Wild life should not level, but have a set level they start at. Just think of what you can do as a bear. Eat other players in noob area's. Although not world PvP, an exception should be made for those who choose to be a carnivorous creature. What about a guild of deer who enter Cyrodiil and participate in PvP. The trample upon their foe so their leader can be the deer emperor of Tamriel.
Or a band of cliffracers who swoop down upon their unexpecting breton prey.
This has to be the best idea so far. Discuss.
