Well if spottedleaf was a warrior then firestar would have been her mate, and leafpool, and squirrelflight should have never been born which means the power of three would never have been born, and squirrelflight would have never been born which also means alderpaw, and sparkpaw would have never been born. So technically most of the prophecies, and omens would have never came true.
