I've played him in jungle since S4 whenever Riot didn't make absurd jungle related decisions, and he's been amazing to me since, and one of my faves. One of the few reasons I even bother with this game, in fact.
In jungle you get all the farm you need so you can scale well, he brings a lot of dueling power to any lane he ganks, making him a good counter-ganker, or just pass by sustainer, being in jungle means he gets to meele more often and he is a good meta and comp based pick. I could 1v1 adcs or Yasuo and just come out on top unscathed, and he has amazing zoning or team backup, push for objectives and so on.
I would say I love him jungle exactly because he is so good at covering for flaws or tactical mistakes from your team mates, and he can be both passive or aggressive, and he's just a great pick for pubs.
Yes, his kit is actually built more for roaming or solo laning, or a passive playstyle bot requiring coordination, and so what? That means he already HAS his place in the meta, just not the one Riot wants to force feed to us.
He is a strong tank with good damage dealing nonetheless, but who's kit also backs up your team more directly than other tanks, and this overall DOES MAKE HIM UNIQUE! But he's unique in a natural way, not the artificial way Riot wants. He has a niche, but in a fun way, not the "meta" way Riot thinks it actually understands.
See, in other actually intelligent strategy games, it's actually a good, smart desgin to have a champ/deck/build/strategy that does a little bit of everything in a good order and timing, exactly because it matches the flow of the game...It's almost as if it's, dare I say, BALANCED?
No, the only real problem here is Riot's "disssign furrloserfy" for games spectacle sports...
