Because even after they nerfed him once he still remained a top pick and ban in ranked and tournament games. Their PBE idea is a huge nerf though, he's had a bunch of nerfs lately and this one finally hit part of what made him so ridiculous in team fights but it's just too big.

Even from the standpoint of a league player and not someone who loves playing Karthus, to implement this nerf would be massive. No more armor reduction, a percentage reduction which only would increase his damage vs those with lots of MR. Those make him way less destructive in a team fight.
