He has some points. The story was very straight forward, and sometimes I wondered why Vaan and Penelo tagged along for the ride. The main character's purpose on the journey should never be in question.

Vayne should of probably had a bit more interaction with the main party. It makes sense towards the end where says to Ashe.

"Who are you?" Lol I know it was a rhetorical question, but it was fitting. Maybe he should of had some sort of connection with one of the characters. Like when Gabranth aids you, THEN he has some connection with the group. But Gabranth joining at the very end was nessecarry, any earlier would of sucked.

The Judges sort of compensate for Vayne's non-interactivity. Vayne in himself was a good villain, but they should of made him meet the party like once or something.

The Judges are the absolute best villains of all time. As Seterizo or w/e said a few pages ago, they needed more time.
