[Animayhem]

I have but have not really used them in combat. Since my character has one level of shifter if I change I change into the wyrmling.
Before my character was capped at 15 I sometimes used the elemental shape and the shapechanging spell.

Though I believe the helm,armor and sheild properties meld into the animal properties and you do need to cast spells before the change.

I have not played a lycan but the forms for those are decent enough from what I hear.
