recently jungle has got new update on attack speed item, which is currently the strongest item in game in my opinion. All you need to do is get 30 stacks and you can instantly kill almost any champion, regardless the "juggernauts" meta. So i been thinking and the option that came to my mind is that Devourer should be updated to act same as Mejai's, where you would lose some stacks upon death so it would be more balanced item.
Please consider this as a nerf in the next patch. :)
