The skinny Primal weren't weak, but they didn't overflow with as much Essence as the chubbier ones. The weave didn't abandon them but didn't fill their reserves until every corner of their being was filled with Essence. Still, they were strong enough to contend with the Rebels even after they metamorphosed. The Primal had to be more careful now that their Essences could cause more damage.
After all, their Essences were strong enough to destroy Laws and Authorities, something the Primal wanted to prevent if they did not wish to alter the weave too much.
Once a Law or Authority infused into a Divinity was destroyed, the weave would have to be created again from scratch. However, after the weave had been altered, nobody could tell how much the recreation of the Laws and Authorities would change them. Even the recreation of the simplest Laws and Authority could change everything for the better or worse.
