Why its not like the ranking is a special thing. its not a title or anything.
To have stopped it or made a new one would hurt the sport. would make the games less important, as all they have to handle things as they are, and do the best they can, keep things as normal as they can to keep viewers and teams in the game so to speak.
To remove the list will take away from that goal.
Sure its not like anyone think the teams on it is the best ever. but in 5 years or even 2 its not like it matters.
But to remove it would matter now.
Just make sense to have it and keep it since it cost nothing, and dont really matter even if the list would look different if things where normal. the list have no power as such.
