Review Detail of GnawingJackal in Transported to One Piece

Just read chapter one. No MC development apart from his system. Some hopes and dreams about the OP world would have been nice. Maybe some inner monologue about how he made his choices from the system at the very least. The system seems too helpful; he gained a lot of freebies which weren't well considered. The Sharingan, for example, is kind of defunct in a world where observation Haki lets you predict enemy attacks anyway..
