please. no one argue or disagree with my point here because its entirely my opinion and i know it has its flaws.
i advise leveling up to level 100 because you will have around 4,000hp with no junctions which means, by junctioning and using HP+20%, 40% and 80% you can easily reach 9999HP.
focus on squalls strength more than anyone elses because of his trigger that makes his attacks more powerful than anyone elses.
also, always check what magic bosses has because they often have rare magic like full-life which is one of the best spells for junctioning on the game and also they have GFs sometimes.
