Devourer needs to be fixed?

Honestly, the Devourer enchantment is just overpowered. It isn't a fair item, as there is simply no counterplay to it. Any decent jungler can get it sated by 20 minutes, and once it becomes sated, that jungler can simply not be stopped. I'm not saying it has to be removed, in fact I love the idea of the item. Just, the execution was done poorly. I believe that the attack speed should be nerfed, or they could simply increase the amount of stacks needed to sate it. The main reason it is overpowered is because they can get a very powerful item very early in the game, often before the enemy team can get their second main item.

But it is clear that this item is in need of some tune ups. If a half-way decent Xin Zhao gets the item, it will take at least 5 people's undivided focus to kill him, or if a Shyvana gets the item, she could effectively win a 1v3 scenario.

This item needs to be fixed.
