So AD Blitzcrank Jungle is actually kinda good. Here's builds for people who want to try it.

I was browising the champion pages on the wiki and discovered that Blitz had some really outlandish things going on for him, not what you would expect on a support at all. Besides really high base damages with super high AP ratios on Q and ult, his E also scales with AD and his W gives him attack speed, which inspired me to try this out.

His strengths are strong single target clears, great invading potential with enough vision, good item scaling and pick potential. Weaknesses are AOE clears ( unless you decide to go for Hydra ), early game 1v1s, negative snowballing potential and weakness to enemy invades.

You go Fervor with 18/12/0 or 18/0/12, whatever you like more, I'm leveling up this new account and I did just fine with fewer points in the secondary trees. Standard attack speed rune page ( AS quints, AD marks, armor seals and MRperlvl glyphs ) and you max W then either E for more DPS and fighting potential or Q for more pick potential and burst.

I started with Machete and a refillable, then Warrior with red smite, defensive boots, Triforce, Righteous Glory, BotRK and GA.

Oh and so that you know that I'm not just making this up, here are some examples: http://matchhistory.euw.leagueoflegends.com/en/#match-details/EUW1/3252911530/233228366?tab=overview http://matchhistory.euw.leagueoflegends.com/en/#match-details/EUW1/3251908894/233228366?tab=overview http://matchhistory.euw.leagueoflegends.com/en/#match-details/EUW1/3251805679/233228366?tab=overview

I realize that these games were played on a smurf but I feel like they are still valid examples, especially considering that you are able to jungle with this without full runes or masteries and it still kinda works.

I don't know how good it is exactly but it's definitely decent and loads of fun. Highly recommend you to try it out. Let me know how it went or if you have some ideas on how to improve the build.
