Its not healthy for lvl 3 jungle to gank lvl 2 laners...?
But you just shifted it around... now level 3 laners (mid) will invade lvl 2 jungle...?
Junglers dont have turret to hide under and soak exp like laners do. Losing an entire quadrant on first clear is gamelosing devastating, yet thats what Riot has pushed the game into...
