Kayn top isn't viable anymore, yet was supposed to.
https://na.op.gg/champion/kayn/statistics/top So after a patch of completely removing all viability of solo lane Kayn, Kayn can no longer be played top lane. This is an issue, of course, because some people, like myself, enjoyed playing Kayn top lane. Kayn doesn't work so well in the jungle either due to his poor early game.
Of course, Kayn was supposed to be viable top lane. https://www.reddit.com/r/leagueoflegends/comments/6jugvh/kayn_champion_reveal/djh5256/ https://www.reddit.com/r/leagueoflegends/comments/6n39xh/waddup_were_the_rioters_that_did_kayn_ask_us/dk6n095/
There's a fairly easy way to fix this; simply buff the early game orb generation for Kayn. Considering his jungling isn't always fighting people and he doesn't even fight people early while jungling anyways, this would have minimal impact on Kayn jungle and would make solo lane Kayn viable. Keep in mind I'm referring to how Kayn jungle is played in diamond.
