I always thought the idea of a shapeshifter would have been a nice addition. Before the "blessings" and dervish avatars, I always wondered why there wasn't a class that allowed a transformation into say, target foe, certain various animals, and the elites being some kick ass forms like dragons, stone-like behemoths, cerberus, chimeras, etc. Each form would present it's own inherent strengths and weaknesses. I know that a couple of these forms have been suggested as their own separate class, but I didn't see anything about an all encompassing shapeshifter.
Perhaps going by the implemented structure of blessing forms "caster experiences energy degeneration while in form and returns to original form when energy reaches 0"
Armor: base level should be of any caster class (60) while not in form but determinate of what form you are in
Attributes: Primary linked to the rate of energy degeneration caster experiences while in form.
Other attributes pertaining to attack rate, shape mastery (allowing the shape shifting into higher level creatures) and perhaps a line specializing in energy management skills.
Energy: mid range caster based, say 40
