Too many chances for some teams to experiment with their lineups, that's what I'm thinking. That's an advantage. The PL is a fun thing for Supporters, and I like to think most folks like to try to win games in these leagues and not just experiment in "inconsequential" games, but... give a team several games to do all sorts of stuff when losing really doesn't matter, managers can try to figure out optimal lineups, look for advantages in the game, etc. That's too much of an advantage in my opinion.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
