Electrocute is the problem, not certain champions
Pretty much any mage who whiffs their skillshots can still get away with winning a fight as long as they manage to proc Electrocute and have ignite.

I don't have clips, but a Lux, Brand, Ziggs, Veigar, etc. would all be able to do the same. Granted that the first clip is mainly the fault of the Jhin who didn't get the damage off from any of his abilities or the full effect of his keystone.
I'm not really trying to say that Electrocute Is a problem, so much as I'm trying to say that, contrary to the false conclusion of the threads I actually found these clips on, the champions are not. Any champion would beat Jhin if he lands literally none of his abilities and gets only four auto attacks off, assuming they land all their other abilities like Zoe did. And any champ would kill a Sona they're 4 levels up on with just two of their abilities and ignite.
All you do by complaining that a champion that isn't overpowered is make it so Riot can't take suggestions from the boards seriously. Ignoring the facts, and even lying won't get you your way.
