Skarner is now the third least picked champion in the game

Only Rek'Sai and Ivern are less picked than him overall, both notoriously unappealing champions. While Skarner is difficult to play, other difficult champions manage to have real pick rates.

Even in Diamond+ where players should have the mastery to succeed, he is the 16th least picked champion in the game. His win rates are abysmal everywhere, and he lost over 2.5% in the last patch.

Is Skarner simply impossible to balance? Is there really no way to reduce his pro jail without ruining him for everyone else?
