pentakill favoritism?

is it just me or is out all all the pentakill skins except yorick and karth seem a bit to bland like yeah some of them have new visual fx but karth, yorick and i believe sona are the only ones with different emotes and yorick and karth are the only ones who have some of their emotes play/sing a part of the songs? the other skins should maybe get the same? mord does a sweet riff on recall or something? olaf play a rocking drum solo?
