Duo Jungle

Obviously to prevent the enemy jungler from being able to get ANY farm at ALL

I've done this a couple of times. My most recent duo jung was to prevent a master yi from going sated. My jungler took our jungle, and i bought a poacher's knife into cinderhulk to steal his jungle and i used Sion's passive to steal his camps. He was dead broke by the end of the game and wasn't even close to sated. We also cared for top at the same time. We won the game. I love duoing jungle/top

duo jung is good if you have 1 invaider like shaco and one farmer like ww, shaco can easely farm in enemy jung , but the biggest problem is bot without supp

Well, why didnt the support jus follow him around and help him ward or get the camps? Or maybe bot should be really fed from a 2v1
