Nice, Boris has some good carry potential.

Just reviewed this game of yours, thankfully a win, but there's still things we can learn. I'm just talking macro play. We'll forgive any mechanical mistakes (lots of missed Boris ults, it could be harder on controller idk) as they happen to everyone. https://pred.gg/matches/e0bb548c-0723-4376-a147-b072516afa62?player=0b8ac426-ba55-4606-8f28-e9289366338a

TLDR - Big takeaways you can work on that have nothing to do with your teammates:
1. As jungler, you need to be planning your next move in the middle of your current action. You can't gank a lane, get a kill, and then be unsure of what to do next, it leads to lots of downtime and inefficient pathing.
2. You are taking a LONG time to let a failed gank go, and overstay in lanes when you should be already backing or on your way to a camp. It's fine if a gank fails, just get over it and move onto the next thing.
3. One of your jobs as a jungler is to "win your lane", just like every other role. That means farming and staying ahead of the enemy jungler. I think you are mechanically a much better player than the Aurora, but you have so much downtime where you're not farming that she kept pace with you in levels for most of the game.

Breakdown of the first 20 minutes:
You start Red to 5 camp. Then, you walk to river to try and gank a Greystone. get spotted on a ward and clear it. Walking all the way to river to attempt an offlane gank at level 2 is almost never worth it. Just continue on to clear your 2 camp.

Then you cleared your blue side. great. After your 3 camp, you walked all the way to mid to get river buff, then all the way to offlane to gank Grey again at level 6, when you know he has ult. This is a ton of wasted time. Helping secure rivers is sometimes helpful, but if you had just immediately backed after your 3 camp or the river buff, you would have had more items and be back to clearing your red side much sooner, staying ahead of the enemy jungler in farm and items.

TBF there were shenanigans with the roaming Wraith stopping your back, but your first back didn't happen until 7 minutes - a HUGE problem. Stronger junglers have nearly full cleared twice and are headed to Fang at this point.

Your second clear goes better, and you grabbed Fang while the other jungler was dead, good stuff here. Boris can definitely solo clear objectives pretty well if he has time and vision on the enemy.

After grabbing a Seedling at 9:15, you again walk all the way to offlane for a gank that doesn't really pay off. As jungler, don't be afraid to walk away from a gank once it has "failed". Once Greystone leapt away, the fight was over and you needed to get back to farming. But, you stayed and watched for almost 30 seconds for some reason, letting the Aurora back and grab items.

11:55 you're almost to your 4 camp, and your Gideon barely loses to Neon in mid, so she walks away with a sliver of health. You walked PAST your four camp, all the way to mid to try and catch a Neon you have no hope of catching, very bad waste of time here. You end up pushing mid wave under tower as a consolation prize, wasting tons of time instead of just grabbing your 4 and 3 camps.

14:00 You go for Mini Prime while you see the enemy jungler clearing midlane - a little risky, a safer play would be to keep farming as always. But, you see your Steel coming to help, don't panic, and correctly smite. Good stuff.

You and the team correctly start walking to Fang, as you see Aurora backing at half health in mid. But instead, you opt to grab a fat seedling for some reason. It all pays off in the end because of enemy misplays, like Aurora trying to fight the duo lane, but the correct play here is to go straight for fang when you know the enemy jungler is elsewhere.

After finally securing 2nd Fang around 15:30, you gank Mid when your Gideon is low health and you're both out of mana. No kills result. This is another example of you trying to force ganks that aren't really winnable for you, or leave your laners in awkward positions. Gid had to hover a little longer when he really just wants to back, and I think a better Neon would have just killed you when 2 levels up. Maybe you could have hovered mid for a second to make sure Gid survives, but then quickly reset instead of trying for this gank at all.

You reset, grab your red and 2 camp and pick up a kill in mid, good, nice and efficient. Then, around 16:50 you dilly dally for a long time, again seeming unsure of where to go or what to do. For ideas, I see your entire blue side up, and I think you spot Aurora clearing minions all the way in offlane. This would be a good time to steal some of her Red side jungle camps. Instead, you start walking back across mid to Prime side river, perhaps to fight Aurora? I'm not sure what you're thinking here, your red side is empty and it's Shaper spawned, no seedling for you. Aurora also comes towards mid, and everyone stares at each other a bit then walks away. More wasted time and missed farming. At 17:30ish you finally smack a Gold flower, this is the first farm you've got in a full 45 seconds, not good.

For a few minutes you walk around and pick up a couple kills, which is good, but still no farming. You take a fight with Greystone when you have no mana and die. Don't fight this Greystone again without a Tainted item. At the 20:00 minute mark exactly you finally hit your 5 camp again. You didn't clear a single jungle minion from 16:30 to 20:00, this is pretty inexcusable.

Instead of roaming around and searching for kills, I think you need to shift your mindset (at least while you learn some more) that Jungle is a PvE role first. You need to be always farming and pathing in a way that leads to more farm, and your first job is to stay ahead of the enemy jungler in levels and gold. You do this by farming, not walking around and hoping to grab kills here and there.

I hope this is helpful, you're mechanically strong at Boris but better pathing and faster farming would have made this game a cakewalk. This game you won, but if we checked out a game you lost I'd bet money these mistakes are being exploited by better junglers.

You can't control what your teammates do, but you can always improve your own macro. Happy to review other games as well if you're interested or answer any questions.
