So a little theory crafting here. I've been just trying different people out jungling in customs, figuring if i can do decent on the first run with no leash they would probably be decent in normals where you usually get a leash of some kind. So I tried one of my personal fav. champ Malz. Tried AP like fiddle, but just went horrible, no sustain plus somewhat long cooldowns made it tough. THEN I said screw it and went full ad Malz. Which has been pretty amazing if you use your spawnlings correctly. Basically you want to spawn him at 1:40 so he's fully upgraded and can tank a good amount of damage. The first clear is a tough, but after 3 and trailblazer it goes pretty smoothly. Basically just throw all three spells at them and watch him tank and do decent damage as well as you auto. Repeat at all camps, obviously blue buff helps a lot. I soloed dragon at 10 min. with just trailblazer, tear, and long sword. basically at that point you can blaze through your jungle very fast, taking minimal damage.
On top of that ganks are pretty nice with his ulti too. just walk into the lane spam spells and ulti, and let the other guy do free damage. Make sure you have a spawnling spawned, because they will do a lot of damage while your in your ulti.
Obviously I have no real games to back this up, but it has been pretty fun trying different, abnormal things in the new jungle.
