Lee sin needs to be removed from the game at least till Master/Challenger.
You made a decent elo Diamond 5 what ever and you decided that the hero you played for making that elo was not that skilled as you thought(graves).You start searching on google different tops of junglers for different patches and surprised you see in every top that lee sin appears there(WHAT A SURPRISE).You got sick of people telling you that if you are 10-0 on graves you are not actually a good jungler and you decided to play something skilled,something with outplay in blood and from this moment lee sin is your main.You start watching exclusive streamers like gripex,after hours and hours of watching his stream you start your first ranked game.Not a surprise,you fail miserably being 1-9-9 min min 17 having mobi boots and tiamat.After games and games you realise that your winrate is over 47% in 200 games and you come on boards crying cause lee sin needs a huge buff on everything,because he is such a skilled hero but so powerless(such a powerless hero after 3-0 the entire early game and mid game is yours if you manage to play correctly).You end up being a miserable person spamming slogans like "Get out of my jungle","Cy@" or "better jungler wins" bannable things in my opinion lossing the game even if you are 10-0 cause "lee sin needs a buff".Wake up kids,its not a shame to play heroes easier than lee sin in the jungle and winning with a good kda(everyone in the enemy team spamming things to tilt you),its a shame to overrate your iq/skill and failing.
