just because eiko gets higher level white magic earlier doesnt make her better. you can get curaga easily with garnet. some people just assume eiko is instantly better because she starts with cura. garnet has more powerful summons.eiko may have stronger white magic but with garnet i can easily heal 4,000HP and over with a curaga which is more than enough. garnet is a bit underrated. amarant is also very underrated. his attacks can do heavy damage with the right weapon and he has aura which is one of the most useful spells on the game. and against strong bosses his attack that changes the enemys weakness is very useful. fighting isnt his strongest point but his skills make him very good for passive abilities and support. i usually use zidane, amarant, garnet and vivi. i dont use quina much. hes good and very useful but ive never really been one to go around and collect blue magic. his attacks are sometimes a little annoying. id like to know a damage formula for quinas attacks because i remember doing 2,000+ damage with one attack and doing about 86 damage with the next. quinas blue magic like mighty gaurd is very useful though. quinas still the character i use the least.
