Paul was the best person for the job when it came to guiding them to new areas. Although he wasn't as knowledgeable as Freddy and had never been on this planet before, there were many times in the past where he would be required to lead a team and explore a new planet.
On top of this, because of his high rank, they would often be some of the most dangerous planets. But back then he had his full power, while now it was safe to say he was weaker than before.
