Jayce's Animations are STILL broken

Hi, I submitted this 6 months ago and the problem still exists, so I'll repost this since Jayce is getting some attention with upcoming buffs.

Jayce's weapon no longer has any animations and is static. To show what I mean, here's a quick webm.

Notice how in the first segment (live servers) casting Q does not make the cannon expand or contract in any way, while the ability preview in the client shows a nice animation when being cast.

Another example is in auto attacks. The cannon form clearly stays static when attacking, when it should be expanding and moving.

(I tested this with debonair Jayce since it's clearer to see, but this issue affects all skins.)

Can these be fixed? That would be great.
