What you need to do is only setting this on the script:
// Settings
.ThirdClass = false; // Enable third classes?
.RebirthClass = true; // Enable rebirth classes?
.SecondExpanded = false; // Enable new expanded second classes: Ex. Super Novice, Kagerou/Oboro, Rebellion?
.BabyNovice = true; // Enable Baby novice classes? Disable it if you like player must have parent to get job baby.
.BabyClass = true; // Enable Baby classes?
.BabyThird = false; // Enable Baby third classes?
.BabyExpanded = false; // Enable Baby Expanded classes: Ex. Baby Ninja, Baby Taekwon, etc.
.BabySummoner = false; // Enable Baby Summoner?
.LastJob = true; // Enforce linear class changes?
.SkillPointCheck = true; // Force player to use up all skill points?
.Platinum = true; // Get platinum skills automatically?
.GetJobEquip = true; // Get job equipment (mostly weapons) on job change?
Hope it help. ?
