How to Fix Jungle Diversity
I posted this on Reddit but I figured I would also put it here where more other people can offer their thoughts/opinions:
Give Hunter's Machete a new passive that deals area damage to monsters in combat with the jungler each second, slowly stacking damage over time. Riot can calibrate the number so that it matches slightly below a decent clear time. If a low-damage jungler (such as a tank) is lacking on damage, the item will slowly compensate that damage while clearing a camp.
Give the new passive a small ratio that scales off of bonus health and damage mitigated, which means that as tanky junglers get tankier, their clear time speeds up as well. Not absurdly so, but enough that they do not fall far behind fast-clear junglers.
Below is a mock example, and would need definite number tuning. It is merely to give a picture of what it might look like.
Jungler's Resolve: Deals 2 (+2% bonus health)(+10% damage mitigated (potentially)) damage every half second to non-epic jungle monsters, increasing by 2 damage each second that the jungler remains in combat with the camp.
Once the numbers are tweaked, this effectively creates a minimum clear speed floor that Riot can balance. At a certain point (say 20 seconds, just as an example) the damage of the passive will ramp up and effectively finish off the camp if the jungler's damage is too weak to do so. If a jungler is very fast at clearing, they will have already cleared the camp before the damage can ramp up, keeping the passive useful for slower-clear junglers without simply speeding up junglers that were already comfortable in the new jungle.
PLEASE NOTE: The speed from the Jungler's Resolve passive would be balanced to be an average clear speed. It does not mean every slow jungler can clear like a pro. All it does is ensure that low-damage tank and utility junglers are able to keep from falling heavily behind to meta junglers.
