How does Riot justify this "Devourer" item?

Feral flare was already bad enough. Now with this new jungler item that doesnt even really require any wind-up time the jungle is dominated by on hit champions like warwick and xin zhao. Does riot even play test this stuff? How did they look at that and go "yup yup, wont break the game at all" they could have asked any silver or even bronze player if that item looked like a good idea and they would have been met with an adamant shaking of the head and a hearty "Silly riot".
