Seriously. The first season I was ever gold was season 3 and I got Victorious Elise, who at the time was my favorite character of all time and I felt so happy. Since then we have had Sivir, who I don't play, Morgana, who I don't play, and Maokai, who I don't play and who wasn't even remotely on the map when they released him. The Graves skin is the same probably, Graves has been off the map for a while and they are still releasing it like it's a relevant skin to the meta like Victorious skins used to be.
Next season they should have a website where a mass vote is held for the class (except ADC and Jungler because they already have two skins) and then a vote is held for a champion who doesn't have a skin yet. Each season they just remove the previous season's class from the vote until they go through all 5 lanes. The only issue with this is that characters like Kindred, Bard, Yorick, etc., will never even have a slight chance to get a skin, but then again they have basically always just picked season 1 or 2 champions who are classic to the game anyways. Ironically, Elise is still the newest character to get a victorious skin which is absolutely stupid, they should pick a character from the last couple years or so rather than always going back to the classics.
