Hunter's machete needs spell vamp with the lifesteal against monsters
Currently many champs are limited from being able to jungle effectively because there is not enough sustain open to them.
While this might not help the ADC junglers which I have seen a few of as of late I will say that AP champs have a darn hard time in junglecurrently.
It is a simple fix but would make the jungle a bit more open to some other options which are not currently idea for jungle.
