there is nothing wrong with leveling and it makes stat increasing easier because if you learn an abitlity which upgrades a stat on level up you can get those stats high and if you are at lvl 100 it is easier to upgrade hp because you already have about 3000.
but low levels can be good too because if you are at level one through the whole game and are very goog at juntioning you will be invincible.omega weopon willl only have 110015 hp or something like that and seifer should have on his first fight only about 157 hp making the game quite easy.either coice is good but level 1 can make the game too easy so i go at high levelswhich still makes it easy because FF8 if you are good at it its the easiest FF ever.
