Learning the jungle role can be difficult, and the understanding of pathing and priority are some of the toughest parts of the game to pick up on. Because of that, there are some jungle champions in League of Legends that beginner players should avoid in order to assure their win.
Wukong’s weakness as a jungle champion is in his ganks

Wukong can be a rather powerful champion in League of Legends when played correctly and can offer a lot to his team. However, learning his playstyle can be difficult for players new to the jungle role. This is because most new players want to focus on the early game and make ganks to help their laners.
While this may work when used correctly, it is important to know that his ganks can be predictable and easy for opponents to escape from. Because of this, it can throw a new player off balance if they do not know how to recover from an unsuccessful gank.
Elise needs to land skillshots

Elise is a jungle champion that shows a lot of potential, but picking her up can be difficult for new players. Because Elise is an early game champion, she wants to make sure to hit her early level three power spike and move to make multiple ganks from there to ensure her teammates can carry into the late game.
However, it can be difficult for new players to learn this strategy: since she is so squishy early on and relies on skillshots, she can easily lose momentum if players do not know when to gank or how to correctly position herself for those ganks.
Skarner can’t get to the enemy backline

Since Skarner isn’t a very powerful jungle champion, playing him and understanding how to properly use his kit in League of Legends can be difficult. Skarner’s goal is to move onto the enemy backline with his slew of movement speed abilities and lock them out of a fight with his ultimate. Trying to make a flank or a flash play like that can be difficult for new players. Because of this, new players best focus their attention to jungle champions that can help them learn the role instead.
Kindred needs to make risky plays as a jungle champion

Kindred can be a difficult jungle champion to pick up in League of Legends because players must properly know how to make the most of her passive in order to use her to her highest potential. She will often have to invade the enemy jungle to get her marks. However, because the marks are visible to all players, she can easily be countered and picked off when trying something sneaky. It is also important to note that her ultimate can outright lose a teamfight if used incorrectly. If trying to save one ally means losing an entire fight, then it is best not to use it at all, which can be difficult for new players to get the hang of.
Nidalee requires a lot of early kiting

Nidalee requires a lot of game experience in order to play her correctly. One issue she has is that she is very squishy and requires kiting her camps in order to stay healthy, which can be difficult for new players. She also is an easy target for crowd control, so if an opponent jumps on her and locks her down, she is out of the game. While she can be powerful if played optimally, new players will find Nidalee much more difficult than other, more welcoming champions.
