Jayce is still missing animations and effects on all of his skins (including classic)

I was looking at the Full Metal Jayce skin preview and I decided to try the skin in game since I hadn't used it in quite some time, and I noticed that many of the particle effects where missing/wrong.

On all of his skins:

-Jayce is missing ''recoil'' animations on his Mercury Hammer form when he auto attacks or casts spells (this bug was introduced when Forsaken Jayce came out).

-E1: Thundering Blow: Lacks the electricity/static energy that follows Jayce's hammer whilst he swings. 1:13 on the Champion Spotlight (notice the electric after effect). 1:02 on the Skin Spotlight for Full Metal Jayce (notice the static energy after effect).

On Full Metal Jayce:

-W2: Hyper Charge; uses Classic Jayce's Hyper Charge textures (yellow/electric) instead of Full Metal's (blue/static energy). 1:32 on the Champion Spotlight. 1:15 on the Skin Spotlight for Full Metal Jayce.
