Champions on that rotation are usually either new champs or champs that Riot wants to give new players to give them a hand at trying out the game. Basically safe and new champs are on rotation.

And apparantly Poppy and Yorick weren't safe or new. Now Karma was also one who almost never appeared of free weeks. When she got reworked that got changed.
