He also fills every requirement to be Sona's husband. He isn't dumb, although Vali hasn't shown any advanced strategy while fighting, it doesn't mean he can't, i doubt that someone like him who reads a lot of books of any sort doesn't have a good couple of strategies down his sleeve. but he hasn't shown any of that because he prefers to fight more or less head on, giving freedom to his teammates to do whatever they want. The other requirements are to be stronger than Serafall which isn't that difficult for most of the cast, but beating Sirzechs in a duel it's something that out of the young generation only Issei or Vali can do it.
