Jungle Urgot
Not so bad. Can clear 5 camps with no leash grabbing both buffs before back with half mana and 20-30% health. I usually recall at 3 to improve ganking and make the jungle a push over though. His clear is fast enough to stay 1 level ahead of side lanes and even with mid. After getting jungle upgrade he doesn't have health problems and after getting tear he doesn't have mana problems. If you get a gank resources stop mattering in jungle at level 4 or level 5 without a gank. His perma slow is pretty oppressive and his lock on out ranges flash in most cases.
I've been going full ARP red, 8 armor and 1 flat at attack yellow,full flat attack blue, and full armor purple. Gets me 12 armor pen, 3 attack and 18 armor. More armor is over kill but less armor made me take damage ( felt like a big transition between 12-18 armor for whatever reason). Masteries are 9 offense and 21 defense.
Start at toad, then wolves, then blue buff. Level 3. Go for gank mid or whatever toad lane is. pass or fail recall and upgrade hunter item, do red side. Level 4. Gank each lane unless pushed. Rinse repeat. Item priority has been Hunter item level 2, tear, boots then you just go on from there. It looks like tear, hunter item ARP version, ice gauntlet and black cleaver.
Items usually this:

I sell the hunter item off at some point for another tank item. He never makes full use of the true damage window but it adds enough early game to not matter. May ditch muramana for angel specter instead. it depends on if the carry is actually doing damage. Zhonyas, Warmogs, and spirit visage are all interesting choices too to tank with. It's really hard to fit health into his build and still get his other stats covered. I haven't looked at the new items much but they may be good on urgot too.
Urgot still has a lot of his weaknesses but it's hard to starve on gold in jungle and his perma slow ganks are pretty nice. A lot more fun than laning him.
