The biggest issue with the new model is not the aesthetics of it but the multitude of animation bugs it introduced to both succession and awakening wizard. Several slides now occur at the end of animations that move your character around unintentionally and there has been no recognition of these issues in the offical known issues list.
Some bugs I noticed...try taking your awakening weapon out, and switching running left and right quickly, your character will do a spin in static regular running animation (you'll notice something is weird at first, it happens fast, but definitely noticeable).
Try crouching, one of your legs is gonna bend as if it was becoming a tentacle...Guess wizard is a Cthullu worshipper now...
If you made your wizard max height, enjoy having to adjust your camera every single loading screen if you want to look at your character's face or something.
Several of the animations they claim they made for this new model, are not actually new, they just took several of the witch's animations and slapped them onto the wizard.
