@Riot, when you rework Cassiopeia again, please fix her death animation
It's no secret to anyone that has ever played Cassiopeia that when she dies and turns into stone she's transformed back to her old classic model. The only skin that does not do this is Jade Fang.
Here are the videos showing it for every skin (jump to the end): Siren: https://youtu.be/wDlwhPMrd_k?t=154
Desperada: https://youtu.be/PMwe1WfNTus?t=142 (In my opinion the worst one, notice how her hat simply vanishes)
Mythic: https://youtu.be/AsVw5a19YcE?t=160 (This is even more outrageous on a 975 skin)
Even her classic model turns back into her model pre visual update: https://youtu.be/hYfZes01l2E?list=PLrum9hQsVLkJGD4kaIziFl22qBu456Tji&t=144
Here is Jade Fang for comparison: https://youtu.be/AzNELknAZiQ?t=165
People have been asking for this to be fixed for over two years, before her first rework/visual update.
So please, Riot. Remember to fix this.
Thank you, from an old Cass lover! 
EDIT: Important but off-topic
I just read up on the Aurelion Sol (Ao Shin) update and saw that you guys were working on the engineering for the movements of a serpentine body. I'm not sure if he's still going to be a serpetine dragon. BUT, in case this engineering has been perfected, could you also please make Cassiopeia's movement more serpent-like? Her body model feels extremely awkward in movement.
People have been dreaming about this ever since Vel'koz was released with his amazing tentacles.
So thanks again, Riot.
