Should smite be necessary for jungling?
What if smite was optional on junglers?
So jungle monsters will have to be easier to kill in general, and smite would be used for faster clear and better objective control. Junglers will be able to take things like ghost/flash, exhaust/ghost, or exhaust/ignite for better ganks, if they can clear well.
I think this may help with jungle diversity, and solve the "jungler forgot smite" issue.
