No. There are a few champions way on top, the champions who can survive against those top picks, and then the niche and unviable picks.
The go to picks are
is straight up the best tank, crowding out almost every other pick
basically makes picking any jungler that isn't an early game beast a death sentence. Lee Sin mark 2. (Honestly, moving her into the jungle was one of the worst decisions I have seen made by this game).
manages to stay relevant largely because she counters the the two above, and Tremor Sense is always useful.
Otherwise
has a good enough early game that invading him is often suicide.
is good for camping and initiation.
is good for ambushes and suprise attacks.
is basically an AD version of Nidalee with a roundhouse kick.
is very good at abusing pretty much any overtuned item in the game.
Meanwhile,
(and several others)
are all champions who have seen success in the jungle in the past, but now serve little purpose. Either they are outclassed by others in their role, they are crowded out due to their weak early clears, or they have simply been nerfed into unviability.
"I can't pick Amumu, they will just pick Lee or Nid and then kill me."
"Why should I pick Sejuani if Gragas exists?"
"Aatrox would be a PERFECT pick here... if he did anything."
Not to say that any of these are BAD jungle picks (except Aatrox, he just sucks). They are simply niche. Jarvan provides great initiation, good durability, and good damage; he is a good champion, but why pick him over Gragas, who does the same things? Why pick Shaco to pressure early when you could pick Nidalee and do it twice as well?
