I believe that when someone completes a hard raid (summoner or staudt) that the prizes for yellow crystals is too low, considering the effort put forth on a 6th planet grants the same amount as summoner or staudt hard. Many on the facebook Time World agree that the yellow/green crystals should either be taken out, or give a higher amount to give a better feeling of satisfaction. Please respond and offer feedback on this topic!
