Skarner is freelo
I remember when everyone cried when Riot "gutted him". Meanwhile Skarner has maintained at least a 50% win rate ever since his rework (54% currently). It's funny how, as usual, the boards are wrong about everything. He still has mobility, he can still tank with his shield, still has his slow (even though it's not a perma slow anymore), he still has a suppress with no channel time (unlike Malzahar), and he has decent damage. On top of all this, he has his Crystals which makes him one of (if not the best) duelists in the jungle. Even though he lost his permaslow, Riot has done a lot for Skarner and I'm honestly surprised they haven't nerfed him harder. Anyways, just play him. You won't be disappointed.
