I'm going to be honest, when i jungle and take a champion that will benefit from sated i usually find that rushing out devourer stacks benefits more in the long run than ganking as long at my teams lanes aren't being completely demolished.
-yes its bad practice
-yes its stupid and i know I'm not contributing to the early game.
but the power spike that this stupid item affords is just absurdly hilarious and it becomes a race to finish the item so that you can get the first dragon in and end up way ahead of the enemy jungler, who anymore will inevitably be getting the same item. seriously a grand GRAND majority of other junglers i see are all working to finish up this item as quickly as possible as well because it just affords your champion so much extra damage from its passive. its especially stupid on udyr, diana, xin, and yi. heck i was playing as attack speed diana and DELETING THE ENEMY TANK. its even better if you build tanky AP with devouer and a nashors.
the item rewards a selfish playstyle, and in turn rewards the player with a power spike of utterly stupid proportions in some cases.
on your topic, if you increased the stacks needed then unfortunately i still feel that it was more worth it to farm up devourer so that i can jump in on the enemy adc and annihilate them and more easily secure dragon and other objectives. seriously i can melt towers with this item as well.
do i enjoy using it? yes.
does it make it a healthy item? oh heck no. im all in favor of removing this thing, but i will have fun until that point comes.
