Also, some of the most annoying characters ever, prior to SO4.
The good thing though is you could just not recruit Roger and Peppita (I'm assuming you mean them).
That's already praise worthy if the game allows you to ditch characters you hate. I know I would have loved that option in many a game.
P.S. If you also meant Adray... I would have agreed with you had I not seen his ending. Funny enough, one of the lamest character has one of the best endings.
