I don't care, it has to be said
Sated devourer has made this game BORING. There has not been a single damn game I go into where a Devourer champ wasn't picked. One of three things happens pretty much every game. One of our team autolocks Yi and goes the Devourer route, but gets destroyed early and has absolutely no impact on the game, because either they had a better champion for Devourer (Shyvana, Kayle), or just didn't grasp how to use Devourer properly. They get a good lead early and carry the game (Which is fine every now and then) or our team doesn't take a Devourer Champion at all, gets outscaled by AFK farming, and we lose. Please, please, PLEASE look at this item. I don't want to quit playing this game but the current playstyle it promotes may just drive me to do it...
tl;dr Sated devourer is causing the game to spoil with how binary it's caused the game to become

While they may never be super popular, their kits are just that you can build them as a damage oriented bruisers (three damage items, two defensive items, as opposed to the one or two damage and three to four defensive for a defensive oriented bruiser).
Also, while not the most popular, they have a way of sticking around in almost all metas.
