About the Skarner rework and crystals, why not turn them to an item to be upgraded at shop instead?

I dunno why they don't let him as he is and make some minor QoL changes (like E cast not slowing him for example). I believe those stuff along nerfing his Q right after his last rework is what is missing him.

About the crystals, I like the idea. I really do. But they way they are is badly executed, along with nerfing him to the ground in almost every aspect. Why you don't make the crystals like items you can buy at shop, and allow him to put where he wants. If it's needed to make the crystals less powerful (which probably do), then do it. The game of crystals would remain, would still something unique and would been even more fun for the Skarner players, since they could decide where to be stronger. Finally, you had the possibility of also having more buildpaths, by deciding if you should or not buy the crystals.
