GF's will give you a sore thumb
1. learn Hp-J, Str-J ect so you can raise your stats with magic.
2. Draw as much as you feel like.
3. Junction the magic to your characters.
Next after that I would learn refine abilities. So far everyone has said the first time they played they relied on GFs so your not adnormal there. If you have a hard time with drawing, boost your magic as high as you can get, set your curser to memory in config, go fight desired enemy. Draw what you want with each character and tape or hold down the ok button.
GF's will always hit more (well most of the time) but they also take longer. So if your dealing half of the damage your GFs do, remember you can attack a lot faster. So its your choice.
