Sated Devourer and Feral Flare

First let me say I like being able to be strong as a jungler and I enjoy these types of items which you eventually get a spike in the same way manamune and AA staff spike your power.

Second I want to unequivically state that Feral Flare on release was the worst patch in league of legends history after season 0.

Most players dislike infinitely stacking items(and abilities). They require you keep on powering up and there is little counterplay if they are powerful. Since the only counterplay is winning hard and stripping all creeps away so he cannot stack, something which can only be done when winning already.

Because of the nature of the item being INCREDIBLY powerful when finished instead of merely a modest bump in strength or a powerful active it simply skyrockets your effectiveness (Not unlike manamune).

What if I told you that the problem with sated devourer isn't sated, its the methods in which it stacks. Sated devourer naturally spawns 4 stacks on your side about every 90 seconds and 2 more stacks through buffs every 5 minutes. For those curious it would take about 10:30 seconds to stack on your side if you cleared things as they spawned. This is not a trivial task and as such non shyvana junglers can expect it around ~20 doing this. The real problem with the item is dragon and SPECIFICALLY crab. Dragon giving 5 stacks is the ultimate incarnation of "Win More" for junglers because if you are doing dragon you are likely winning giving 5 stacks is absurd and cuts nearly 2 minutes off your stacks. Doing dragon also likely means you did crab for 2 more stacks.

TLDR; Reduce the stacks for dragon to 2 or possibly 3, reduce the crab stacks to 1.
