Why not a "Runic Shield" Mastery for Junglers on Hunter's Machete
Why not include a built in Runic Shield Mastery, which absorbs lets say 100 damage from only Jungle Camps. This shield passive is only for the Machete which refreshes on death.
Basically a quick way to allow only Junglers a cushion on the first few camps, then passive is removed once the Jungle item is upgraded.
