Sated seems like poor item design to me
Broken in low level play were champions can free farm.
Probably a bit too strong in Solo where co-ordination isn't there to shut it down hard.
Utterly useless in organized play.
It's the stacking mechanic that's the problem, really. If it didn't stack and just did its thing right from the gate, Riot could actually balance around that. But as it stands, Sated is going to continue being a problem in lower level play and a trap-option in professional.
Or in other words, no one is happy with it.
