Have you heard of character development? So what if his DxD form is weakened, he now has a chance to get stronger and evolve in order to better master his new form. In regards to your preference of MC, all I'm going to say is that Vali is a stereotypical, one-dimensional, shonen character who barely has any character development, in summary Vali while a badass IS BORING. I rather have a character like Issei who evolves as a character, has a multi-dimensional personality, faults and all.
