Query: Why Raistlin had to lose his power......

Weis and Hickman had to make Raistlin lose his power......If Raistlin still had his power...the battle against Chaos would have easily been won. There would have been no need for Palin or Steel. The Gray Robes would have been destroyed by Raistlin.By making Raistlin weak and powerless allowed Weis and Hickman to actually make a story out of this plot.
