Most of the shapes are small animals and herbivores.
Anyway I see that the avenger, feels like an Avenger, between spells like misty step, to channel divinity Abjure Enemy and Oath of Enimity. The only problem is the Avenger steals the Favoured Souls stuff again at level 20, The 20th level power undermines and blocks the Avenger feel because it comes at rhe expense of the Oath of Enimty.
I'd replace the level 20 CD with the ability to get two enemies with Oath of Enimity.
And it needs an oath feature some where between 8th level and 18th.
The Druids new wildshape seems find.
