Personal Daily Reminder For Skarner Revert
Same thing as always, just put a CD between slows on affected targets. he was more of a juggernaut then than he is now. Fundamental problem with new passive is that a champ shouldnt be VIABLE around their objectives, they should be STRONG or BUFFED around their objectives.
For example - Illaoi is strong without sticking to her objectives (tentacles) cause they spawn around her and she can spawn untargetable temporary ones with ult and she does good damage alone with autos and q and e. Skarner doesn't get ANY benefits or upsides when not around spires. Thats REALLY bad for someone who cant scale without hard items. The rework didnt even solve the original issue with skarner. Kind of a slap in the face, didn't even get feedback before changing him.
That concludes today's daily reminder for Skarner Revert. 
EDIT: Their main issue was the fact he would come to lane and ult and dip back into jg until ult was back up. Usually only ganking with ult. I ganked more often though pre 6 and without ult BEFORE the rework cause e and crystal venom could still make good palys. E now is miss it, no ganks. If i missed ol E i can still run into their face and stun with crystal venom.
