There appears to be what I sincerely hope are some bugs with the new wizard body and animations. Both in Succession and Awakening, but I think this maybe impacting all animations to some regard as they all feel just ever so slightly longer.

The bug: When casting certain spells your character will do the proper animation and then at the very end slide slightly in a given direction. This slide will actually cause you to fall off of ledges and changes the position of your character from the start of the animation to the end, when prior to the body change it did not.

There are 5, easily reproducible, scenarios in which the bug is most prevalent:
1. Prime Earth's Response: Destruction to the Left V.S.  the Right.
   - If you cast Prime Earth's Response: Destruction to the RIGHT the CORRECT animation will play WITHOUT a slide at the end. As seen here: https://gyazo.com/41b7223d3f8161b8574480d34ecc2f78
   - If you cast Earth's Response: Destruction to the LEFT you will notice at the end of the animation that the character model slides forward slightly while standing upright. As seen here:

2. Prime Fireball - The same slide occurs when you cast fireball - at the end your character slides forward slightly. As seen here: https://gyazo.com/92eb62729da66f3145797b44cdcabebc

3. Prime Earth's Response: Flow - A slight slide to the left or the right is present at the end of the animation for this skill regardless of what direction you use it in as you can see here: https://gyazo.com/4f0205d0f00fb8d61b370029bd8c461c
4. Water Sphere III - Your character slides forward slightly with every cast of Water III with or without the flow, as you can see here:

5. Magma Bomb - The same slide that occurs in Water Sphere III occurs when casting Magma Bomb. As seen here:

Notes on Testing and Reproducing the Bug:
I did test these skills on Witch and this does NOT occur on Witch using the same skills. 
This bug is present at all levels of the affected succession skills - i.e. Prime Fireball I, Prime Fireball II, and Prime Fireball III. 
This issue does NOT occur in the Skill Demo animation window, for any of the affected skills - the skill demo and the game do not match. 
I suspect that this is an error due to the new body rig and the animation is not properly ending in the proper neutral position for the character thus resulting in the slide? Just a guess.

Special thanks to @Huntler who also discovered this and covers the issue well in his video here:

After further testing I did find this issue in certain awakening skills as well, and I have edited and updated the report above to reflect that. 

Water sphere moved you slightly forward on cast before the remake aswell. Think they did that change shortly after awakening was added to stop ppl in RBF from standing on the rooftops spamming it or somehting like that.

I believe the same applies to witch's W+F skill thats also ranged and spammable.
