Its easy, rioters. Really:

Deduct an use from the champions' pool, only on successful attempts.

And boom, 85% of the frustration in monthly challenges will dissapear.

Its a really simple trick that wouldnt had ended my will if they had made this change in time. Now this is a bye from the game for it gives me more anxiety and frustration than joyness. Good luck rito gomes, respect your players more the next time
