What if we put together a Undead Druid set.
Tauren male/female - Undead male/female
Bearform - Undead bear out of Western Plague Lands
Catform - Undead wolf from Felwood or Western Plague Lands
Travelform - Undead boar from Western Plague Lands
Flight - Any of the bats (if you have a better model to use, please suggest it. ^^)
If I had any skill at crafting these packs or anything, I'd do it myself and contribute.
Hopefully someone with some skill could pull this off.
