Mecha Sion and chroma idea

Just wanted to complain again in hopes of riot noticing that Mecha Sion has no chromas, but even aatrox has chromas.

Also, I have an idea. I feel like people would beeven more likely to buy chromas if they changed the color of particles as well. They wouldn't need to change the ability design itself but change the color of the ability, vs the idea of a skin changing both color and shape. Not to say people don't buy chromas, but it would still be cool if Dragonslayer braum could shoot green to match a chroma instead of orange
