I'm not entirely sure why, but I am flamed most of the time I pick yi in the jungle. Now this isn't a qq thread, I just want to know why the prejudice? Thank you for the feedback, it helps me learn more about the game and helps with
Regardless of what people say, if you are good with him (and keep practicing despite the hate) then use him. People want the jungler to have CC and be tanky so that they have free range to pick any champion they want:
Team A;
A team with bare minimum CC.
It is actually kind of selfish. Junglers like Yi, Shaco, Xin are still great. They can split push, counter jungle, and assassinate better. Especially if you instead have a team like:
The only reason why one would need CC with the jungler is to make ganks easier to make for the laner. If both the laner and jungler have CC, then it's considered a done deal. But the mindset of most playing now is that tanks are amazing in the jungle, there isn't a dire need to have damage.
You'll notice the trend of competitive games and streamers often do poorly against split push comps. People are forgetting how multiple playstyles affect each other.
I actually had a game two days ago where the jungler went 
. I thought the game was going to be easy after counter jungling and getting the kill. Yet somehow, my team could not handle the Kayle and she ended up 9-1-3 before 16 min. Her dmg won the game, and I still have no idea how that happened.
Basically its hard for Yi to hit a point that he is useful to your team and he is incredibly susceptible to CC and in team fight he basically runs in to die. In this meta its not okay for you to not gank which is what Yi has to do to become relevant.
Because people want CC with their jungler.
You can get your burst damage for your team from mid and bot lane, but Jungle is where the CC champions tend to come out (and support).
Without CC, it makes his ganks very weak unless his team sets it up perfectly for him.
Yi is a farming jungler people hate those
I see the same problem with both Yi and Warwick. Once you get above level 20 and everyone has runes and masteries the big sustain and clear advantages they had in the jungle over the other junglers vanishes. When you consider that the current meta is tilted towards tanky junglers with a lot of CC, both Yi and Warwick often are unable to 1v1 their counterpart and the fact that both can fall off hard late game means that the team they are on either wins fast or is vulnerable to being outscaled.
Personally I cringe when I see someone try to take Yi into the jungle now. He just doesn't bring enough to the match. I'm reminded of one recent match where I played Sejuani into a Yi jungle. He gave me trouble early game, but by midgame I had built thornmail. Yi killed himself attacking me 3 times. My whole team was laughing at how ineffective he was against me and eventually over most of my team as he was built the usual glass cannon and as long as I managed to engage him he could rarely escape before we bursted him down.
i dont play yi jungle i take him top and just farm till i can tp into a team fight cleanup and get enough kills where i can 1 shot their adc. If that doesnt work i split push. I dont use him jungle because i dont prefer to help people with yi because if i get the kill they rage.
Master Yi has developed a bad name due to his low skill floor. Because of this, many people assume that the user is not actually good with Yi. This means that when you win, you did not earn it, and when you lose, you are terrible with an easy champ, and should uninstall the game. But the reality is while his skill floor is low, his skill ceiling is very high. You can pull off some pretty crazy moves with him if you practice enough. Also, the man is a freakin' Jedi, which is pretty badass. So next time someone complains, just tell yourself haters gonna hate, and say in all chat "Oppa Wuju Style"
Because Yi sucks.
Yi falls into a category of champs (especially in bronze, not sure what rank you are) who are often picked by people who pick them because they are "carry" champs. The hate comes from the experience many players have of the stereotype of who picks those champs. Often people who play yi jungle don't work with their team real well and will talk about how they will carry if you just peel and tank for them, but especially in low ranks this isn't often something they achieve. Thus when playing yi jungle you have a lot of prejudice to overcome. If you are comfortable on yi and work with your team he can be great. Maybe try saying you can play a tank jungle if the team needs, but you are much more comfortable on yi since you play it more. (Which needs to be true so if it is t go play team builder) of course this may mean playing some more tanks in ranked since it is the meta, but may also get more teammates who are all for you playing yi since you seem different and may work with the team
