Fill is for Addicts Who Can't Bring Themselves to Do Literally ANYTHING Else!
League is a video game.
One of an infinite number of things that could occupy my time.
So, I see no logical point in having that time consumed by playing it when it assigns me a role I have no interest in playing.
I think I will go now and microwave me a tasty snack and then watch a cartoon or something while downing a beer to accompany said snack.
Yeah, that sounds a fuck ton better than playing a filled role on a VIDEO GAME!
