Era challenge. Finally a challenge!

And CG Just sits there in their silence and does nothing

They just released an announcement about an adjustment. But whether it addresses this issue is another question.

They are providing more rewards on each tier BUT they are no addressing the point that this challenges are very challenging! Jajaja. Challenging!
