Help on Kayn

Hi I’m a kayn main since December of 2017 currently holding m7 idk how many points in kayn

This is the one champion i have truly put my time and effort but of course I am not the most perfect kayn player out there, ik there are ppl better than me and I will never be the best, but I want to be good with him,so I made this post to help me get better at him and rhaast

So my questions with Kayn

What is the best set of runes to take with him

I usually take these

Domination: Electrocute Sudden Impact Eyeball collection Ravenous hunter

Ppl say run dark harvest idk why I think electrocute is better but plz tell me why in some ways dark harvest is better

For secondary

Precision: Triumph and Legend: Tenacity I usually take this set on rhaast but lately I haven’t been winning games with it recently so suggestions on using this tree or how to utilize it will help

Sorcery: Celerity and Waterwalking I use this for both rhaast and kayn because it helps me roam a lot faster and get my form but idk if it’s worth taking due to the fact I don’t have any extra tankiness

Resolve: Chrysalis and Revitalize for rhaast due to the fact I get better healing/tankiness I have never run resolve on rhaast but should I give it a try

Inspiration: Magic Boots and Cosmic Insight I feel like this will help kayn and rhaast in terms of utility but not sure if o should be using tunes as utility or more health/ damage

For gameplay scenarios here are some problems I have playing kayn or jungle in general

Let’s say all my lanes are pushed up and I can’t get orbs that quickly because i can’t gank My only solution is fighting the jungler but what if the jungler is a good duelist like xin zhao or Warwick As regular kayn I can’t really do much can I? So should I just wait and counter gank or farm like it’s fucking FarmVille?

Hard matchups The champions I have had been trouble jungling against are these

I feel like khazix can snow ball better than kayn because he has that isolation bonus and lots of mobility early game

Nidalee I feel can just snowball better because her ganks seem better than mine same with khazix

Xin zhao almost the same reason he has better early game dueling/ganking/ farming

Hecarim He ganks faster which leads to him snowballing better

Hard matchups out of jungling phase

Garen how tf do I beat this guy he has a silence execute and consistent dmg and he’s super tanky ik rhaast is a tank slayer but I just feel super useless when fighting a garen

Akali she has a lot of dashes and a smoke screen that not lets me ult her should I just avoid her unless she has smoke screen down

Leblanc same reason as akali almost she just out maneuvers me in a lot of ways

What if one of my lanes end up feeding? Do I gank them by myself? What if mid lane can’t help because they are going bot while top is asking for assistance when they are lvl 8 and I’m lvl 8 and the enemy is lvl 11

My last question is what do I do when I’m behind?

Thank u for reading this of course any kayn tips will help me in the long run I just honestly want to get better at him and I have been REALLY rusty with him lately and just want to get out of that state
