Which junglers would you like to see in the meta?

The fantasy is that every jungler can be viable and equal, but since that can't happen let's consider which ones we'd rather be top tier in the near future.

Sion: Fun mechanics, good interaction and counterplay in his Q.

Jarvan: A good early-game terror and his ult is interesting to have in a game (unless you're bronze, in which case RIP he's helping).

Elise: Mechanically interesting and she works thematically.

Maoki: He's actually literally a tree.

Warwick: Also works thematically, but he should be a noob pick instead of the ridiculousness he had in 4.20.

Kha: Interesting champion, he should continue to exist as a high-skillcap assassin that needs to snowball to be worthwhile.

Lee: Keep him viable, but make him like Kha, in that he really needs to snowball.

Mumu: Another good noob pick, he should be able to farm to 6 and then press-R-win-game, but make him really vulnerable to invades early.

Shaco: Interesting champ, just being in the game is enough to change how people play.

Nunu: Pure evil, but really interactive with the enemy team if they try to stop his counterjungling. He should be the ideal Poacher's Knife fantasy. What he needs to be strong, IMO, is a change to his Q so that consuming the birds extends the duration of his true sight.

Udyr: A more agressive Nunu. Although I might be okay with him getting gutted if the trick2garmy keeps trying to powerfarm with him.

Xin: Fun mechanics for the jungle, ult is an interesting gank tool.

Aatrox: Great champion, just needs a change so that he doesn't default to 50% hp whenever he goes into the jungle. Or make him a bit less squishy early because that passive isn't really useful for ganks outside of tower diving, which you don't always want to try.

Nautilus: Ridiculous ganks but easy to bully, and a lot of interaction in that you have to kill his shield to stop his dps.

Diana: The ult is interesting, I don't know much about her play patterns though.

Rek'Sai: Has the potential to be a great jungler (but IMO she's a really unhealthy toplaner).

Sej: I mostly want to see her new skin someday.

Vi: All-around good champ with interaction and counterplay.

Fiddles: Always makes the game more interesting, whether you're playing as him or against him.

Zyra: I wish this was still a thing.

The ones I left, I left because either I don't see them enough to have an opinion on whether they're healthy for the game, or because I don't feel like seeing them in the next any-time-ever. Feel free to share your thoughts.
