Except you can't about the Orc part. They used the Dragon Soul which was empowered by double the 4 other Aspects power(the original empowerment and the empowerment again in our time).
Also it's funny people keep bringing up that Velen vision and then ignoring when people in the post say "if a normal eredar can destroy a planet, why didn't Archimonde do it on Azeroth or Draenor when he visited each one"
