Apparent Amarant
Blue Mage
Except for GF. GFs take to long and cause too little damage. I never even junction the GF command, and always junction ITEM instead (or CARD), because it gives you more options.
This isn't true if you don't AP whore in the beginning. My GF's would often cause like 2000-4500 damage with my characters doing about 200-280 on the beginning and middle of disk 2. Thats pretty invaluable especially when you use them your party member can't take damage.
