My favourite nuke animation is Stone III. It felt impactful and the WHM stayed on the ground and had a nice wide stance instead of doing this awkward hip dangle thing I came to despise. Aero 3 and Holy looked nice, I loved the magical girl staff twirl of Aero 3 and I like the animation in the air much better than we currently have.
The new animations are all random sparkles and that's it. No impact behind it, I dislike the casting animation itself and then there's the flimsy little flower with the windchime sound for Misery.

Afflatus Purgation on the other hand... now that is an animation that makes you feel the impact and would've been much better for Misery then what we ended up getting. The flower motif with a giant laser shooting out and the WHM doing this "In your face!" spread is perfect.

It's sad that the "powerhouse" has the least impressive and impactful animations across the board, both for dps and healing.
