In the past few years, Yuumi has probably been the champion that has caused Riot Games the most trouble in balancing and editing.
Yuumi was remade by Riot in version 13.5 with a completely new passive
However, after about 8 months of being remade, Yuumi still shows many `inadequacies` in terms of gameplay.
The community pointed straight at Yuumi as Riot’s worst rework this year
First, League of Legends gamers think that the idea of making Yuumi an accessible and player-friendly champion is a bad idea.
The `freeloading` mechanism from Yuumi is not the basic gameplay of League of Legends
Next, the way the Yuumi remake was implemented was also considered a complete failure.
The ability to enhance Q based on critical strike rate makes the number of champions paired with this character quite limited.
However, Yuumi continued to fail when falling into normal ranked matches.
That’s why editing Yuumi in a player-friendly way is a terrible idea.
Yuumi currently has a relatively low win rate, even at Assassin rank
In short, with the wrong decisions from Riot, Yuumi is currently becoming an extremely weak champion after more than 8 months of rework.
