League of Legends Champion Syndromes

It has come to my attention that many champs create different syndromes within the player playing him/her. Some of the syndromes that I have noticed include:

Pantheon Syndrome: Gets extremely fed early, but then feels the need to go ham ALL OF THE TIME. Eventually leading to a throw and the flaming of the whole allied team.

Rengar Syndrome: "I do not care if I am fed or not, if I click R.. I'm going in."

Vayne Syndrome: The player is typically not good with vayne, but do not fret for he/she will always say these words.. "I just need to farm for late game". Whether it works or not, these words will be said.

Vi Syndrome: He/She will Flash--Dash--Ultimate. The Vi player then begins to ask, "Where is the follow up?". Most likely leading to an immense amount of rage, and enough to throw the game because she has created so much commotion that she has single handily tilted the whole team. NO, this person has created so much commotion, he/she has tilted the enemy team as well.

Teemo Syndrome: There are a number of different kinds of "Teemo Syndromes. They range from the " I am tilting, so I pick teemo" to the "I think I am a spawn of Satan, so I will play this champ". Regardless, this person will absolutely feed if they are on your team, and smash your team if they are on the opposing team.

There are many more, but I want to hear what you guys have noticed/seen. Comment below!
