Need help finding s5 good junglers

God tier: Lee Sin, Jarvan, Vi, Nidalee Tier 2: Rek'Sai, Pantheon, Wukong, Rengar Tier 3: Kha'Zix, Sejuani, Amumu, Rammus, Rumble

Relevance of opinion:

• Gold II jungle main (Last season, haven't ranked yet this season)
• Have mained jungle ever since the end of season 1

B3ER's list is pretty good.

Personally I would add Olaf to top tier and Fiddlesticks is probably Tier 2. And Diana, Yi, and Warwick are probably Tier 3.

There is a big ol list. I probably don't need to mention this, but I figure I should put out the spoiler all the same: Don't just blindly pick the 'best' jungler. Make sure it fits your team comp. Shen might be good if they have a pantheon, or chogath if they have katarina, or a poppy if you really need burst, even if they aren't listed as top tier.
