[GAMEPLAY] Mecha Malphite's chroma skins are missing the best effects on his W

So for those who don't know, with the Mecha Malphite skin when you use your W it gives him those really cool looking spikes on his fists.

The thing is, I just bought his Sandstone chroma skin and when you use your W there's literally nothing that changes on Malphite. I haven't noticed if other particles/effects were missing other than this one. I haven't tried for any of his others chroma skin since I don't own them.
