20-30 minutes? People don't brainlessly rush the jungle to finish stacks asap.
The item itself is awesome for many champions that benefit from stacking effects due to attack speed. It's pretty common for a SD jungler to finish it around 20minutes and still have a lane presence.
I have not seen a sated jungler get it by 20 minutes while having lane presence unless my team was retarded as shit and just die to every devourer jgler gank/give drag for free. Most sated devourer jungler have shit gank pattern and most of the time will afk farm unless they see a really good opportunity to gank and hope that the gank go well.
Putting pressure early will force him to get out of jungle to put pressure or risk his lane losing. When you have a losing lane as devourer jgler is suck because most of the time you won't get camp for stacks. It's either your team farming your jungle or the enemy stealing your jungle.
