I have to say nobody use these skill (except those who want some fun).
Because it’s not good at all. The monster transformation is too weak to be DPS or Tank.
and more over, you can’t use any of your skill in monster form.
So this is my suggest.
1.Change [Transform] to a skill that allow you to Transform to a animal/plant type Boss by using Boss card.
Make It’s work the same way with of Sorcerer “Ride” skill, but without summon and animal/plant type Boss only.
2.Change the effected target of [Shape Shifting]. so, instead of transform yourself, make it transform your Companion.
This will make you useless companion some how better and still can use all of your skill.
3.Add a skill that allow you to Transform your companion back to the last monster your companion Shape Shifting to
This skill should have only 1Max Lv , the duration is depend on [Shape Shifting] skill.
