What champion do you think caused the most chaos when they were released? Things like how OP someone might have been or how much they singlehandedly changed or broke the game.
Edit: It seems that many of you have decided on Xin Zhao, so I went and found this video from a few years ago that goes over why release Xin was such a behemoth.
External link →Old pantheon could 100-0 you under your tower without tanking a single tower shot, and new pantheon could do the exact same thing cuz his E could block tower shots. Akali rework on release made her INVISIBLE under tower in her W and made tower drop aggro. But Xin Zhao was FAR worse on release. As far as game-breaking goes, Viego has caused more bugs than any other champ.
There's no way Viego caused more bugs than Yorick, especially pre-rework. I never did the analysis but I'd bet money there was a point in time where Yorick cost Riot more money than he made.
In the same line, Anivia had a fantastic bug where if you sent her Q off the map from the spawn platform it detonated globally. Like Kayn’s W a few years ago. All enemies and minions took damage and were stunned.
I believe this one was a coordinate underflow bug where getting the negative coordinates on the map would basically make it hit all the coordinates on the map.
I think it was similar to that weird Jax bug where he could Leap Strike to stuff like dragon but in a way where he had the exact same coordinates and so that caused abilities that used coordinates to have Div 0 errors among other crazy things.
