I'm not even gonna bother jungling anymore
Season 5 "diversity" has made every other jungler garbage for no reason. Nothing needed to be changed in season 4. Admit it. Jungle was balanced. Tanks had quill coat. Spirit stone gave sustain. Madred into FF gave farm junglers a purpose to farm (and later was nerfed so it wasn't broken but was viable on certain champs still). Not enough clear with spirit stone? You can still get madreds with an upgraded spirit item. Not enough sustain (namely mana) with madreds? You can get spirit stone even with Feral Flare! Are you a tank who wont gain from attack speed but still needs a way to clear? Quill coat is the solution? Smite, the ability used to clear camps and secure dragon and baron (original and still current description: "Deals 390-1000 true damage (depending on champion level) to target epic or large monster or enemy minion). It also makes no sense that you can't smite small creatures. It's my smite let me kill that little one since it was countered and I don't want to waste time over there.
Also, smite, the ability meant to be used only for camps, minions, and objective creatures, couldn't be used to double as a dragon/baron securer, but also have 1) the slow of exhaust on a shorter cooldown, 2) more true damage than ignite, 3) nobody cares about poachers but Nunu, 4) the exact healing function from the original smite with a mediocre AoE.
And in the only jungle you could play anything. Yes anything. I saw AP Feral Flare Viktor jungle carry me to victory when every lane did poorly. That was before the rework that made Hex core better. I saw pretty much everything work in Season 4 jungle. Lucian? Saw it. Zac? Saw it. Thresh? Saw it. Alistar? Saw it. Jinx? Saw it. LeBlanc? Leona? Kayle? Garen? Janna? YOU WOULDN'T BELIEVE THE SH*T I SAW.
**TL;DR: **With "more diversity," even champions designed to jungle and only to jungle, specifically Evelynn, aren't even viable, especially if you're fighting Lee Sin, Jarvan, or Rek'Sai.
