i heard that the grigoris were affected by the fall but since they fed on souls their broken wings were healed over time and that grigoris can beat seraph without feeding on souls because the were some of the first angels made protect earth and Castiel was back at full power when he fought Tamiel, he just can't teleport anymore.
