The dead warriors can awaken new warriors by transferring their own potential to the living and awakening theirs with it. This is possible because races with Paragons are beyond social creatures. They have a bond akin to a spiritual network that connects all of them. They can be connected even with their dead.
This method of awakening has ensured the existence of paragons within their race. The stronger the totem, the more paragons can be awakened. And since only Paragons can become vitality core stage and more, the Warrogs have been able to maintain some level of strength.
The fact that they are still able to awaken paragons despite the curse on them is a silver lining. Which pack leader will not be satisfied? But the harm has already been done. The Warrogs don't have access to their main divine ability anymore. Their Paragons are but empty vessels compared to the ancient paragons.
