Skarner changes... Meh?

I'm a huge fan of Skarner. I played him so much before the rework, after the rework, bought most of his skins except the Shurima one.

I like the health-scaling "W" that promotes tankiness on Skarner and that they moved the old passive stun to the "E". They buffed his ult too, which puts a bit more power and differentiation from the frog .

I am not sure about this new passive. They nerfed his base MS and took the ramping AS and MS off of his Q. This moves most of his power toward the passive spires. The passive would be okay if it wasn't so easy to deny him these stats. He's either very strong or very weak so the strategy is quite simple: take the crystals, delete the jungler. The other champs have changes that may slightly revamp their play styles but Skarner's just seems like a mini game. I'll have to wait and see, but is this incredibly fair?
