All Jungle Smite Upgrades should allow a useful Smite against Champions
has shown us that having an offensive oriented spell trumps anything else but its also good to have a Smite oriented bonus as well
So I propose the following changes to buff up the other 3 items so they are equally valid and relevant
now applies grievous wounds to the target and applies to single target spells as well as Autos. This smite bonus also works on Monsters.
Heal reduced to 10% and no longer restores Mana but now heals you for 6-10% of Enemy champ's current health
Can steal enemy jungler's buffs from them for extended duration and now gives 1000 true sight around the camp you smited for 3 seconds
Steals 40% MS for 1 second instead of 20% for 2 seconds and steals that same amount as Attack Speed from Monsters
