How did you defeat bosses? Did you use magic or just spam limit breaks? Or something else?
Before Lionheart, I junctioned magic to Squall's STR to get it to 255 and then let him take damage on purpose to spam whatever limit he had at the time, while Zell used magic and Quistis just did whatever (Drew magic or healed when necessary) After I got Lionheart and Aura, I just spammed Limit Breaks to defeat Bosses quite easily.
