To Be A Good Jungle...

1. You must be capable of ganking three lanes simultaneously and repeatedly. Solo the enemy Jungle at the same time for bonus points.
2. You must drop 8 wards, including 2 pink wards, clear all wards dropped by enemies, and always pinpoint the enemy Jungle with your Farsight before level 9.
3. You must solo every dragon within 5 seconds of it landing and kill Baron before the 20-minute mark, also solo.

Do all these things, and you will be a good Jungle. Unless your team loses, then it's still your fault.
