That's a personal choice I guess. I found I loved champions after one game: Rammus, Shen, Gragas, Xerath... All of them I played on free week.

And if they did it only with the champions you don't own, it would mean rich people or long time players would get a skin in no time flat. I have friends that own ~95 champions. That means they play like 20 games and they get a skin? That's not fair.
