Remember that this is largely opinion and it is not based on the best jungle PICKS since that is highly objective and subject to opinion. This list is taking into account the potential of characters to jungle on their own regards to make measuring their capabilities easier.
Tier 3 – Kayle, Gragas, Twitch, Fizz, Galio, Renekton, Rumble, Fiora, Pantheon, Singed, Twisted Fate, Janna, Blitzcrank, Kennen, Taric, Sion, Ezreal, Soraka, Karthus, Cassiopeia, Lulu, Ziggs, Leona, Heimerdinger, Brand, Yorick, Evelynn, Mordekaiser
For tiers 1 and 2 - the placement is more important towards indicating "who is better" but less so for tier 3. In tier 3, just think of it in brackets as the champions here are more flawed and harder to argue. You can say that the higher tier 3 champions are better than the lower tier 3 though. For Tier 4 and 5 it's pretty much wishy washy.
Some people seem to be getting confused with the ranking. It should be obvious by seeing who gets the S scores that S means higher than A.
S scoring is just some video game thing used to say things like “Oh man you are amazing” etc etc. It’s most commonly used in arcade type games.
Btw before I go on I'll just state who it think some of the best PICKS are at the moment. The obvious Mundo and Nocturne (due to tournament player) are there as well as Nautilus (for teams) and Olaf for counter picking-jungle carry status. Lee Sin is always a safe one while Udyr tends to be binary depending on the competency of your team. When all else fails - pick the all purpose Jarvan.
The things that have changed this time around
Warwick + Shen - The duo of "wait till it gets to level 6" junglers have moved up due to the fact while they may have some glaring flaws such as weak pre 6 ganks (warwick) and sluggish speed (Shen) they are very powerful in other aspects such as sustain, pathing, resilience, item variety and then become even godlier at level 6. They are also cheaper junglers!
Jax - He moved up as Gangplank is simply outdated now and weaker. Jax still has a rev up time as his noticeable flaw but once he's got that truck started he runs down most of his opposition rather brutally.
Mordekaiser - Honestly he can't gank but someone brought up a good point. At least he's faster, doesn't rely on mana, has great clears and a lot of people don't want to face him 1v1 so why not just bring him out of tier 5.
Shaco - I still want to hear more arguments as to why he should go down or go up. I've been getting messages from both sides.
Amumu - One of the junglers with the highest win ratios in the game. In terms of solo queue picks even idiots know to go in when you press R. He's a very fast jungler, his level 6 ganks can turn entire games around and he can go several builds. He does have the weakness of everyone wanting to kill him and that his ultimate is on a long cooldown. Still though he is underestimated to an almost criminal level.
Nocturne - Moved up because he's being used more and I'm having a tough time dealing with him even with match ups I believed were positive against him. He's able to build tank and still dish out serious damage due to his steroids.
Skarner - Similar to Trundle in that he's a bit antiquated now. Not that he's any worse than before but that everyone seems to either have dashes everywhere or everyone bought boots which is like 99% of the games. This makes Skarner's earlier ganks less reliable but not necessary terrible to the point where you shouldn't try them. It means you just have to bait people into their deaths. In terms of match ups - he does beat a few characters like Lee Sin and Jarvan but not by a margin to seem impressive. A real benefit from Skarner is that he snowballs better than a lot of other junglers. If he gets a few kills early he will become difficult to kill, fast and mobile, deal high amounts of damage and will exert high amounts of CC including his ultimate. Skarner is a good "carry" jungler if you may. he may not become a murder machine like Olaf but he becomes a terror machine.
Note* - Udyr, while powerful and versatile, may soon go through the same.
Olaf - He's one of the few true carry junglers in the game and he can run amok if not kept in check. Pretty much no jungler can stand up to an olaf that is double buffed and in good health. If he can land his axes then they're either death or crippled beyond recovery. He's fast, he clears fast, he speeds up, he's efficient with his gold and is one of the most brutal counter picks to junglers like Nautilus, Maokai and even Shyvana. As explained before he does have the weakness of being restricted by mana so that always has to be managed well. He also has the weakness of being able to be shut down due to this mana restrictions and the enemy team taking advantage of that and keeping him down and unable to function. Olaf is basically a ticking time bomb and the enemy team can work their magic to make it so that bomb gets some extra wait time.
And the new champion - Draven
This is where he can't gloat. Simply put ranged AD characters can't really be junglers. There are some niche exceptions like Ezreal (due to his skillshots) and Twitch (because he focuses on ganking non stop) but Draven has neither of their stuff. Ranged AD have a tough time dueling due to line of sight issues in the jungle which would force them to get face to face with their opponents and likely give the enemy the advantage by doing so. Draven is also slow, has no real ganking tools and would have weak resilience. He at least can maintain himself due to the nature of his Q and has some sustain points there.
