I would like to add though that point is sort of weakened by Issei already beating people who outclass him in other areas like Vali, i.e. Issei's magic is terrible, but he still beats people with magic. Vali and Issei are similiar in nature but not attack type, Issei is purely Power-Type while Vali's seems a little more focused on Magic due to the nature of his Immense Demonic Power, Divine Dividing's nature, and his talents in magic. In fact, he's known as the Devil Archmage by ExE, so its questionable if you can even properly compare Vali when we know he and Issei are so different. Issei's "power" alone can make a lot of magic irrelevant. I'm not saying Vali is inferior to Issei, I'm just saying he's not necessarily superior either. Just because you are balanced in this world isn't necessarily a good thing. Sometimes, raw power defeats things like strategy and a balanced skill set.
