change to juggernaut enchantment?

So i play a lot of jungle and i dont see anyone take the juggernaut enchantment. I usually bring warriors or devour because of the champs i play. I was thinking of how to make the juggernaut enchantment more viable. For every large monster killed your health is increased by 50 health. Of course not being a rioter i dont know how much health it should be, but you get the idea something that makes it stronger the longer the game goes on. Sorry if this wasnt typed well I'm not a common forumer.
