To me as a final boss I never felt he was so hard to beat. The first time I beat him I didn't even try that hard and I beat him. Of course he has epic battle music but I really wanted a challenge with Kefka but I felt let down. I even tried not using summons magic spells or anything that would make the fight easier and I still beat him without much trouble. Does anyone feel like the difficulty could have been upped to make Kefka a lot harder?
