"We hate junglers who farm all game"

It stops gaining stacks once it's Sated, though, so that at least solves the "farming all game" part. The thing gets Sated fairly quickly if you play decently, I think.

The new problem is the "become Death, destroyer of worlds" part once it's Sated, though.

Every time they "fix" a jungle item it completely destroys the fun of the game for everyone who isn't using it.

They specifically changed Devourer so that you didn't have to farm all game with it anymore. They made it stronger and also made it so that you don't actually spend all game farming anymore. It makes perfect sense for them to do that if they don't want junglers farming all game.
