Your Personal "Kryptonite" Champion
Who's the Champion you hate to play against the most? Your "kryptonite". I'm not talking about the stereotypical 
, 
, 
and 
, because, let's be honest here, everyone hates them. No, I am talking about the champion that you personally hate playing against, so much so that you consider dodging when you see the enemy team pick him, and even tryhard your ass off in Normals just to win lane against that champion.
For me, personally, it's 
. If any of my friends (all 2 of them :^) ) want to trigger me, they say the name Swain. If one of my friends wants to destroy our friendship, he picks Swain. And it all actually started when I was low level, played a champion I had no idea how to play as and got matched against a High-Elo Swain player who I had no idea how to play against.
(Do keep in mind, this isn't a hate thread on Swain, it's just that I have no idea how to play against him yes it is a hate thread Rito pls remove)
I am so thankful she's fallen out of meta cause whenever I face her she always becomes unstoppable. Unless she's on my team. Then she's a glorified minion.
. I see this champ on my team, I know he's going to suck BALLS. When I see him the other team, he's a fuckn god that just refuses to die.
A good Darius is nothing to be messed with and even the crappiest Darius player can give me trouble. It's like playing against a Teemo, It's not that its difficult to do, it just takes a lot more concentration to defeat.
fuck this guy
I hate her ultimate so much as an assasin main with juggernauts/divers being a close second, Every god dam game Ive been against Lulu, I wanted to commit a genocide of Lulu mains, THAT GOD DAM FORSAKEN ULTIMATE
because as a 
-main I know I'm in for a poke-poke-poke-poke hell of a laning phase. Other ranged Supports can poke me too, but none of them seem as punishing as her for some reason. Add to that she is also quite adept at protecting her ADC.
