Best tips to climb out of bronze playing jungle

Camp one lane, get the opponent tilted. Instant Win.

I don't really play jungle, but from what I've seen, the Yi's that tend to do the best are ones that build Bloodrazor into Titanic, Deadmans, maybe even Frozen Mallet. The idea being that you do a ton of damage while being tanky, so you don't instantly die if you eat one thing of CC. This also works for splitpushing later if your team is dumb, because Titanic offers good waveclear so you can push waves relatively quick without needing to use all your mana on the wave.

For Shaco, just camp a lane and be annoying. Buy Mobi's so you get more distance out of your Deceive, allowing you to surprise targets from a further range.

I'm not sure what to do for Graves. Haven't seen him much lately. He used to be a sorta off tank with DD and Phantom Dancer. The few times I've seen him now he has Ghostblade and Duskblade, but again, those games haven't been that good.

Bronze is it's own kinda thing. People make a lot of mistakes that you can take advantage of if you notice them. As a support main for instance, people will go out of their way to try and dodge a Blitz Q if you walk at them, so as the Blitz player, you can literally walk up to half of them and just use E into Q for a guaranteed grabbed instead of hoping you hit that skillshot at max range while they are dodging. Obviously you can still try to do max range hooks as Blitz, but it's not necessary half the time. Look for these types of things.

Look at the minimap. Your jungle camps really don't change much, so as long as you aren't at 100 hp, you can afford to spend some time looking at the minimap. If you see something, try to ping it or keep it in mind. You can see the Scyrers Bloom on the map, so if you see it popped, ping the location.

Look for a pushed lane. Most Yasuo's I've seen will push their lane, so if you see a Yasuo top, start at your bot side buff to ensure you're top side around 4 minutes into the game so you can gank him. Additionally, do you have a Yasuo on your team, maybe try to be on that side of the map around 4 minutes in incase he gets ganked so you can countergank it.

Look for the enemy jungler. Is he ganking top lane while you do your bot buff? That means he isn't there to contest you at dragon. Obviously you might need your teammates to help kill it, but that's something you should be looking at. If you can't do dragon, maybe gank bot or mid, since you know their jungler can't countergank you.

Look at the jungler when he shows on the map. Does he have a buff? You can assume that most junglers will start their bot buff cause bot lane will give the best leash. There are some exceptions: Ivern can start whatever camp he wants; Kayn, Eve, Hecarim, Olaf, Rengar, Amumu can start Raptors easily without a leash; Amumu, Olaf, Hecarim might start blue cause they are mana hungry early. If they decide to gank level 2 for some reason, they might not have had time to get their second buff yet, meaning you could possibly go counter jungle it from them, putting them behind for ganking.

IF you want to get technical, you can look at the CS the jungler has early game and have an idea what camps he took. Buffs, Gromp, and Scuttle are 1 cs, Wolves are 3, Raptors are 6, Krugs are 10. So if someone shows up with 8 CS and 2 buffs around 4 minutes, they most likely did Raptors and both buffs. Which means you could possibly go counter jungle their Wolves, Gromp, and/or Krugs if you wanted.

Know what you need to dodge. As Yi, you have a built in dodge with your Q, so don't instantly Q when they get in range. Use your ult and run at your target, only using Q to dodge something. As a Nami, I will run from a Master Yi, using my ult to disengage so he uses Q either to catch back up to me or to dodge my ult, and then I use my bubble to catch him when he comes out of Alpha. As a Yi, don't do that. You need to dodge the Q, not the ult.

If you really want tips, look up videos on Youtube or see if there is a streamer that plays those champs and watch them play. Hopefully find someone informational so they can explain why they are making the decisions they are making.

Foxdrop is a jungler I watch who explains some of what he does, but he tends to play kinda random stuff, so I don't know if he has a recent video about any of those champs.

Another good youtuber to watch is Prismal_lol on Twitch or Prismal on Youtube. He is insanely informative, which is really intense if you aren't used to looking at the game that way. The downside is he is an ADC main, so he might not know much about jungle, but he can probably offer some advice if you message him during a stream cause he's a challenger player, so he has a lot of game knowledge.
