People who take fun modes too seriously need to calm down

Like Legend of the Poro King. I told everyone in the Champ Selection that I was going full AD Garen. I warned I wasn't going to be a tank. Things didn't go well and a Fizz, who was doing even worse than me started talking shit. How I was trolling, how I shouldn't do this there, how I should do this only with other 4 friends, how he wasn't having fun because we were losing, how it was my fault that he was dying so much because I made him "not even try anymore." Like damn I was trying my best. I didn't troll a single moment. I played seriously with an unusual build that I wanted to try and have fun with. But instead this person, and then followed by the rest of the team, turned it into a no-fun situation with their actual harassment.

Poro King is a fun mode just like URF or Doom Bots. Unless a player is going afk or actually trolling to die in purpose (like Fizz was actually doind after blaming me of doing it) just sit down and try to have some fun even when you lose.

Those people should really never play fun modes.
