I think you guy's just want over-kill. For having his powers for only a year, Issei is already powerful enough. He does need to develop his demonic powers. I am not talking Vali level but rather, he used 8 pawn pieces, so as he presently SUCKS with demonic powers, just develop them to not suck so much. That would be enough for a while. Really what he needs is to sit down and play some strategy games to develop, well, strategy and tactics. Learn different ways to use what he has and how to use the abilities of those around him.
